chore: bump version to 1.5.18

* feat(admin): align turnstone-admin DB config with server (config.toml + env)

turnstone-admin previously read TURNSTONE_DB_* env vars only, forcing
operators with credentials in config.toml to re-export them just to
run admin commands. Wire add_config_arg + apply_config(["database"])
into main() so admin honors the same precedence as turnstone-server:
CLI / config.toml [database] > TURNSTONE_DB_* env > hardcoded defaults.

Also exposes pool_size + sslmode/sslrootcert/sslcert/sslkey to admin,
which previously dropped any such config silently.

Hardening: load_config() now warns once when config.toml is group- or
world-readable, since DB password and TLS key paths live in [database].

Tests cover precedence (default / config / env / partial fallback /
empty-string-in-config-beats-env), the real init_storage boundary on
a tmp sqlite path, the sys.argv -> main() pre-parser path, and the
new permission check (mode 0644 warns, 0600 quiet).

* test(admin): unify config import style in test_admin_db_config

Use module alias (config_mod.apply_config) instead of mixing
'import turnstone.core.config as config_mod' with 'from
turnstone.core.config import apply_config'.  Addresses
github-code-quality bot feedback on PR #531.

-| `SkillKind.INTERACTIVE` | `"interactive"` | Authored for the interactive maker persona (single-workstream "do this"). |
-| `SkillKind.COORDINATOR` | `"coordinator"` | Authored for the orchestrator persona (delegate, monitor, synthesise).    |
-| `SkillKind.ANY`         | `"any"`         | Either surface (or audience-neutral).  Default on create.                 |
+| `SkillKind` enum     | Stored as                   | Visible in                                                                |

+The `kind` field is a `StrEnum` — drop-in ``str`` compatible — so
+DB rows, JSON payloads, and `==` comparisons all work without
+translation at the edge.
 
-**`kind` is metadata, not an enforcement boundary.**  The model can
-`skills(action='find')` across every kind from any session, `get` any
-row by name, and `load` any visible skill regardless of session kind.
-Actual runtime capability is gated by `allowed_tools` + `auto_approve`
-on the skill and the operator's approval card on every `load` /
-`spawn_workstream(skill=...)` decision — `kind` doesn't add or remove
-any of that.  It's a sorting / grouping / search-narrowing hint.
+When a coordinator calls `list_skills`, the SQL filter narrows to
+`kind IN ('coordinator', 'any')`.  When an interactive session picks
+a skill at activation, the filter narrows to
+`kind IN ('interactive', 'any')`.  A skill author tags once at
+creation; the two surfaces stay partitioned without any
+per-call filtering on the LLM side.
 
-The opt-in filter is on `skills(action='find', kind='coordinator')`
-(or `'interactive'`) — pass it when you want to narrow a catalog
-browse to a specific authored audience.  Omitting it (or passing
-`kind='any'`) returns the full catalog.  When supplied, the storage
-filter widens to `[<kind>, 'any']` so audience-neutral rows remain
-visible inside the narrowed view.
-
-**Tagging a new skill as coordinator-targeted** — set `kind` to
-`SkillKind.COORDINATOR` (or the literal `"coordinator"`) when you
-`skills(action='create', kind='coordinator', ...)` or POST to
-`/v1/api/admin/skills`.  Use this to signal intent to other skill
-authors and to make the orchestrator-targeted catalog easy to
-browse — not to hide the skill from interactive sessions.  Existing
-rows default to `SkillKind.ANY`; bump them to `COORDINATOR` if
-you've rewritten the prompt around the orchestrator toolset and
-want the kind filter to surface them as such.

-       every other site uses ``createElement`` + ``textContent`` +
-       ``append`` / ``replaceChildren``.  Missing escapes are
-       structurally impossible — no HTML string is ever interpolated.
-    2. **Sink-free string-concat** (``console/static/admin.js``,
-       ``console/static/governance.js``): operator-facing admin /
-       governance pages still build HTML via ``escapeHtml`` + string
-       concat, but the unsafe sink is off the call site (everything
-       routes through ``setSafeHtml``).  XSS defence still depends on
-       every interpolated value going through escapeHtml; the lint
-       catches the sink but cannot catch a missing escape.
-
-    All admin-side bundles are now covered.
-
-    The regex covers inner/outer-HTML assignment (plain and
-    concat-assignment), ``insertAdjacentHTML``, legacy doc-write, and
-    the dynamic-code constructors (string-eval, dynamic-Function,
-    string-first-arg timer scheduling).  ``insertAdjacentElement`` is

-"""Tests for the xAI / Grok provider.
-
-Covers the boundaries the new code adds:
-
-* Capability-table prefix-match on ``GROK_CAPABILITIES`` (aliases like
-  ``grok-4.3-latest`` resolve to the documented ``grok-4.3`` row).
-* ``XAIProvider._build_kwargs`` merging ``<tool>_call_output`` strings
-  into ``include[]`` alongside the inherited ``reasoning.encrypted_content``
-  entry, so xAI's hidden server-tool outputs become visible.
-* ``resolve_server_side_tools`` folding the legacy
-  ``supports_web_search`` boolean into the effective tuple.
-* ``extra_headers`` forwarding through ``OpenAIResponsesProvider`` and
-  ``OpenAIChatCompletionsProvider`` (Anthropic also accepts the kwarg;
-  its streaming-context-manager shape is exercised by its own existing
-  tests).
-* ``model_registry._detect_openai_compat`` setting ``server_type="xai"``
-  for ``api.x.ai`` and its subdomains (and not for look-alikes).
-* End-to-end wiring via ``create_provider("xai")`` /
-  ``create_client("xai", ...)`` / ``list_known_models("xai")`` /
-  ``lookup_model_capabilities("xai", ...)``.
-
-All tests drive through the real provider; only the OpenAI/Anthropic
-SDK boundary is mocked, and the mock records call kwargs so the body
-shape can be inspected (per the project's
-``feedback_mock_transport_body_inspection`` rule).

-"""LLM-judge stage for the output guard.
-
-Facet 2b of the three-facet intent validation system.  The regex output
-guard (``output_guard.py``) catches blatant patterns; this LLM stage
-catches the domain-camouflaged payloads the regex set misses
-(arXiv:2605.22001 — Llama 3.1 8B evades the regex set on 90% of
-camouflaged prompts).
-
-Design:
-- Single-shot LLM call.  Unlike :class:`IntentJudge` (which gathers
-  evidence over up to 5 turns to judge a pending tool call), evaluating
-  a static tool result doesn't benefit from multi-turn — the text is
-  already in hand.
-- JSON-in-content verdict.  4-strategy parser inlined from
-  :class:`IntentJudge` (``judge.py:1603-1659``).
-- ``ThreadPoolExecutor`` + ``future.result(timeout=)`` with 1 s
-  cancel-event polling.  The executor is owned explicitly with
-  ``shutdown(wait=False, cancel_futures=True)`` so a timeout or
-  cancellation returns promptly even if the worker thread is still
-  blocked on the upstream LLM call.  This mirrors
-  :meth:`IntentJudge._run_judge`'s pattern at ``judge.py:1117-1118``.
-- HTTP client is lazy-init + reused across evaluations on a single
-  judge instance.  Session-side model swaps drop the entire
-  :class:`OutputGuardJudge` (``session.py:1733``/``:2136``), which
-  drops the cached client with it; no separate reset needed.
-- Untrusted tool output is wrapped in per-call random-nonced
-  ``<tool_output_{nonce}>`` fences before reaching the judge LLM, with
-  fence-escape sequences neutralised in the raw text first.  The
-  ``_SYSTEM_PROMPT`` declares the fenced region as untrusted data so
-  the judge does not interpret injected instructions inside.
-- Error/timeout produces an :class:`OutputJudgeVerdict` with non-empty
-  ``error``; callers detect this and fall back to the heuristic
-  assessment.  No exceptions cross the public boundary.

-"""xAI / Grok provider — wraps the OpenAI-compatible Responses surface.
-
-xAI exposes ``/v1/responses`` and ``/v1/chat/completions`` at
-``https://api.x.ai/v1`` with OpenAI-compatible wire shapes; the
-comparison page on docs.x.ai marks Chat Completions as deprecated, so
-this adapter targets Responses only.
-
-The class is a thin subclass of :class:`OpenAIResponsesProvider`:
-
-* No tool-call fidelity-lane override is required.  xAI's ``ToolCall``
-  proto carries no analog to Gemini's ``thought_signature`` — only
-  ``id`` / ``type`` / ``status`` / ``error_message`` / ``function``
-  round-trip through tool calls.
-* Encrypted reasoning replay (``include=["reasoning.encrypted_content"]``)
-  inherits unchanged from the base class — the wire shape mirrors
-  OpenAI o-series.
-* ``parallel_tool_calls`` and ``tool_choice`` shapes match OpenAI
-  exactly, so no per-request rewriting.
-
-Two xAI-specific extensions over the inherited Responses behaviour:
-
-1. **Hidden server-side tool outputs.**  xAI executes ``web_search`` /
-   ``x_search`` / ``code_execution`` / ``collections_search`` on its
-   servers but omits their outputs from the response body by default;
-   callers must opt in via ``include=["<tool>_call_output"]``.  We
-   inject the appropriate ``*_call_output`` strings whenever the
-   capability row declares matching ``server_side_tools``.
-2. **Prompt-cache hinting.**  The ``x-grok-conv-id`` request header
-   maximises cache-hit rate on multi-turn conversations.  This module
-   does not populate it; callers thread it via ``extra_headers`` on
-   :meth:`create_streaming` / :meth:`create_completion` once they
-   know the workstream id.
-
-A static :data:`GROK_CAPABILITIES` table covers the five chat models
-listed at docs.x.ai/developers/models (May 2026).  Aliases such as
-``grok-4.3-latest`` resolve via the existing longest-prefix lookup.
-Bare family aliases (``grok-4``, ``grok-3``) fall through to a
-conservative default so undocumented IDs do not silently inherit
-reasoning-replay behaviour.

-    Default 50000 events.  Two pressures push the cap larger than a
-    casual reading of "how many events does an SSE stream see":
-
-    1. Local-inference deployments stream at 500–2000 tok/s per
-       active model.  Each token is an ``_enqueue`` call, so a single
-       active workstream can fire ~2000 events/sec sustained.  At
-       the 50000 cap that buys ~25 s of pure token streaming before
-       truncation; at typical cloud-provider rates (50–200 events/sec
-       per stream) it's minutes of coverage.
-    2. Browsers throttle the SSE-drain microtask aggressively when
-       the tab isn't visible (Chrome's background-tab budget drops
-       to ~1 wake/min after ~5 min hidden).  A backgrounded tab can
-       legitimately go tens of seconds without draining its
-       EventSource buffer — and PR-G (drop-pings-let-it-die)
-       deliberately closes those connections on hide.  Reconnect-with-
-       replay is the recovery path; if the buffer evicted in the
-       interim, the snapshot floor is all that's left.
-
-    Why not coalesce consecutive content/reasoning tokens?  A naive
-    text-merge breaks the replay-slice semantic: a coalesced entry
-    has the latest ``_event_id`` but text that includes content the
-    client already received under an earlier id, so any consumer
-    with ``last_event_id`` falling INSIDE the coalesced span would
-    double-render.  A correctness-preserving coalesce would need a
-    per-consumer high-water tracker we deliberately don't maintain
-    (consumers register and disconnect independently).  Bigger cap
-    + simple per-event storage avoids the trap.
-
-    Memory cost is ~200–500 bytes per event (deque node + dict
-    overhead + payload), so 50000 × 100-ws design ceiling caps at
-    roughly 2.5 GB worst-case — and practically never anywhere
-    close because the cap is the per-ws ceiling, not per-ws steady-
-    state.  Operators on heavier workloads can raise via
-    ``TURNSTONE_SSE_EVENT_BUFFER_MAX``; below-cap reconnects always
-    hit the replay path, above-cap reconnects fall back to the
-    snapshot recovery floor with an explicit ``replay_truncated``

-* ``arguments`` — JSON list of named positional-argument slots that

-* ``argument_hint`` — display string for autocomplete (e.g.

-* ``reasoning`` — the LLM's free-form explanation. Empty for heuristic rows.
-* ``judge_model`` — the model alias used. Empty for heuristic rows.
-* ``latency_ms`` — wall-clock cost. ``0`` for heuristic rows (regex is
-  microseconds-scale and not separately tracked).
-* ``confidence`` — the LLM's self-reported certainty in ``[0.0, 1.0]``.

-column on those rows is the *baseline* that subsequent feature migrations
-extend (most recently ``040_coord_cluster_admin_perms`` and
-``042_coord_trust_send_perm``).  Some permissions are deliberately
-default-ungranted — ``model.skills.write`` is the motivating case: it gates
-the ``skills(action=create|update|...)`` in-process tool path and an
-operator should consciously opt themselves in before a coordinator session
-can mutate the skill catalog.  Until now there was no UX to grant such a
-permission without dropping into SQL.
-
-This table stores per-(role_id, permission) grant/revoke deltas.  The
-effective set for a role is computed at permission-load time as
-``baseline ∪ {action=grant} − {action=revoke}``; ``roles.permissions``
-stays as today (still the baseline on builtin rows, still the full set on
-custom rows where overrides do not apply).
-
-Composite PK ``(role_id, permission)`` collapses repeat toggles for the
-same permission onto one row.  No FK to ``roles`` — matches the rest of
-the governance schema (migration 008 does not declare FKs either) and
-keeps the postgres dialect aligned with sqlite.
