feat(nous/catalog): add full 24-model curated list for Nous Portal

Matches Hermes Agent's curated model list from inference-api.nousresearch.com.
All models use the nous.{model_id} spec format; parse_model_string strips
the nous. prefix for the API call.

Models: opus47, opus46, sonnet46, kimi26, qwen36p, haiku45, gpt55,
gpt55pro, gpt54mini, gpt54nano, gpt53codex, mimo25pro, hy3, gem3pro,
gem3flash, gem31pro, gem31fl, qwen36b, step35, minimax27, glm51,
grok43, nemotron3, dsv4pro
