chore: bump version to 1.4.0a2

* chore(deps): update dependency hls.js to v1.6.16

* chore: download vendored hls.js files + add hls to workflow detection loop

The wheel-completeness check failed on the Renovate bump because
vendor-js.yml only iterated katex/hljs/mermaid — so hls.js PRs
never got their files auto-downloaded. Adding hls to the loop so
future Renovate bumps are merge-ready without manual intervention.

Also running the update now to fix this specific PR.

+## 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`.

+"""Server compatibility profiles for OpenAI-compatible backends.

+Different local model servers (vLLM, llama.cpp, SGLang) need different
+request shaping.  This module separates two concerns:
+
+1. **Model capabilities** — ``thinking_mode`` and ``thinking_param`` are
+   properties of the *model* (Gemma thinks, Llama doesn't).  These go
+   into the ``capabilities`` dict and flow through ``ModelCapabilities``
+   so the provider can act on them (just like Anthropic's thinking mode).
+
+2. **Server workarounds** — ``extra_body`` overrides like
+   ``skip_special_tokens=false`` are properties of the *server* (vLLM
+   bug workaround).  These stay in ``server_compat`` and get merged
+   into the request's ``extra_body`` at call time.
+
+Profiles are *suggestions* only.  The admin UI auto-fills them on
+Detect; the operator has final say, and the stored DB config is what
+actually gets used at request time.
