feat(models): add anthropic/claude-opus-5.5 to OpenRouter and Nous Portal catalogs

Anthropic released Claude Opus 5.5. Both the OpenRouter catalog and the
Nous Portal /v1/models endpoint serve it (verified with a live max_tokens=16
completion on each route — echoed model matches, usage.cost billed).

- hermes_cli/models_catalog_static.py: opus-5.5 in OPENROUTER_MODELS, above
  opus-5 and below the fable-5 flagship pair. The nous list is derived from
  the OpenRouter tuple, so the Portal picker picks it up from the same edit.
- website/static/api/model-catalog.json: regenerated via
  scripts/build_model_catalog.py.

Provider-agnostic metadata already resolves for the new slug — no edits
needed: DEFAULT_CONTEXT_LENGTHS key claude-opus-5 substring-matches to
1,000,000 (matches live OpenRouter metadata), and the claude-opus-5
reasoning-timeout prefix matches through the "." separator to the 240s
floor. Both routes bill via official_models_api live pricing, so no
_OFFICIAL_DOCS_PRICING snapshot entry.
