Subject: [PATCH] feat(models): add anthropic/claude-opus-5 to OpenRouter and
 Nous Portal catalogs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Anthropic released Claude Opus 5 (+ -fast variant) — both are live on
OpenRouter and the Nous Portal /models endpoint (verified against both
live APIs). Opus 4.8 entries are kept.

- hermes_cli/models.py: opus-5 + opus-5-fast in OPENROUTER_MODELS;
  opus-5 in _PROVIDER_MODELS[nous] (Portal serves both, curated list
  carries the base model like the rest of the Nous Anthropic block).
  Ordering: below fable-5 flagship, above opus-4.8.
- agent/model_metadata.py: claude-opus-5 -> 1M context (matches live
  OpenRouter metadata).
- agent/reasoning_timeouts.py: claude-opus-5 -> 240s stale-timeout
  floor (same as the opus-4.x thinking family).
- website/static/api/model-catalog.json: regenerated via
  scripts/build_model_catalog.py.

Both providers bill via official_models_api (live pricing), so no
_OFFICIAL_DOCS_PRICING snapshot entry is needed for these routes.
