chore: bump version to 1.3.0

* feat: per-model sampling parameters (temperature, max_tokens, reasoning_effort)

Model sampling parameters were global-only settings applied uniformly to
all models. Different models have fundamentally different requirements
(o-series needs no temperature, Anthropic needs temp=1.0 with thinking,
local models may need different max_tokens). This adds per-model overrides
with global fallback so each model definition can specify its own defaults.

Migration 036 adds nullable temperature, max_tokens, reasoning_effort
columns to model_definitions. NULL inherits the global default from
ConfigStore. The session factory and /model switch command both resolve
per-model override → global fallback consistently.

The admin UI model create/edit modal now has dedicated form fields for
these parameters with client-side validation, a visual section divider,
and per-model override hints in the model table rows.

Removes vestigial model.name and model.context_window global settings
(now handled per-model by the model registry) with startup warnings for
existing config.toml users.

* fix: defensive parsing for config.toml per-model sampling params

Wrap temperature/max_tokens conversions in try/except with range
validation. Invalid values log a warning and fall back to None
(inherit global default) instead of aborting registry load.

+## Per-Model Sampling Overrides
+
+The global `model.temperature`, `model.max_tokens`, and `model.reasoning_effort`
+settings serve as cluster-wide defaults. Individual models can override these
+via per-model settings in the `model_definitions` table (admin Models tab).
+
+Resolution order for sampling parameters:
+
+| Priority | Source |
+|----------|--------|
+| 1 (highest) | Per-model override (set in Models tab) |
+| 2 | Global default (set in Settings tab) |
+| 3 | Registry default (code) |
+
+When a per-model override is `NULL` (empty in the UI), the global default is
+used. Switching models via `/model <alias>` re-resolves sampling parameters
+from the new model's overrides or global defaults.
+
+**Removed settings:** `model.name` and `model.context_window` have been removed
+from ConfigStore. Model names and context windows are now configured per-model
+in the Models tab. A startup warning is logged if these keys appear in
+`config.toml`.

+``/v1beta/openai/`` endpoint which is wire-compatible with the OpenAI SDK.
+
+The caller must provide a ``base_url`` pointing at the Gemini endpoint

+:func:`~turnstone.core.providers.create_client` fills in this default
+automatically when ``provider_name="google"`` and no URL is given.
+
+Gemini requires provider-specific fields (e.g. ``thought_signature``)
+to survive the tool-call → tool-result round-trip.  This adapter captures
+the raw SDK tool-call objects via ``provider_blocks`` and reconstructs
+them in ``_prepare_messages`` — the same fidelity pattern used by the
