feat(models): add qwen3.8-max to Nous portal + OpenRouter catalogs, replacing qwen3.7-max

Qwen3.8 Max is live on both OpenRouter and the Nous portal
(qwen/qwen3.8-max, 1M context, 131K max output). Per the
newest-max-replaces-last-max convention, it takes qwen3.7-max's slot
in both curated lists.

- hermes_cli/models.py: OPENROUTER_MODELS + _PROVIDER_MODELS[nous]
  swap qwen/qwen3.7-max -> qwen/qwen3.8-max
- agent/model_metadata.py: DEFAULT_CONTEXT_LENGTHS entry for
  qwen3.8-max at 1,000,000 (verified against OpenRouter live
  metadata and Nous /v1/models 2026-08-03)
- tests/test_empty_model_fallback.py: swap incidental catalog fixture
  to the surviving slug
- website/static/api/model-catalog.json: regenerated

Pricing snapshot skipped: both routes bill via official_models_api
(live pricing), verified with resolve_billing_route. Reasoning
timeout floor already covered by the qwen3 prefix (180s).
