feat: add z-ai/glm-5.2 to OpenRouter and Nous model lists

Z.ai released GLM 5.2 on 2026-06-15, available on OpenRouter:
  - https://openrouter.ai/z-ai/glm-5.2

GLM-5.2 is Z.ai's flagship for long-horizon tasks, shipping a 1M-token
context window (up from 200K on GLM 5.1) and tool calling. Per the
OpenRouter API: text-only, context_length 1048576, tools supported.
No separate -fast variant exists.

The 1M context length, native zai picker entry, setup wizard, and Z.ai
coding-plan auth entries for glm-5.2 already landed on main. This fills
the remaining gap: the two aggregator surfaces where glm-5.1 appears but
glm-5.2 did not.

Changes:

  hermes_cli/models.py
    - Add z-ai/glm-5.2 to the OpenRouter fallback snapshot (OPENROUTER_MODELS)
      and the Nous Portal curated list (_PROVIDER_MODELS["nous"]), newest
      flagship first. Live catalogs surface it automatically when reachable;
      the fallback lists matter when the manifest fetch fails.

  website/static/api/model-catalog.json
    - Regenerated via scripts/build_model_catalog.py (not hand-edited) so the
      manifest stays in sync with the source lists; guarded by
      tests/hermes_cli/test_model_catalog.py.
