chore(models): regenerate the models.dev enrichment snapshot

`xai` and `openai` carry `restrict_to_enriched`, so a live listing id the
enrichment catalog does not know is dropped. The bundled snapshot knew
neither `grok-4.7` nor `gpt-6-astra`, which left both invisible offline
and until the 24h models.dev refresh landed.

Regeneration also tripped the generator's fail-fast: models.dev renamed
the Kimi coding provider. `kimi-for-coding` is now `kimi-code-plan-cn`
(api.kimi.com — kigi's endpoint), with `kimi-code-plan-global` the
api.kimi.ai twin; the model set is unchanged. Both registry rows, the
generator target and the two snapshot lookups follow the new id, and the
cache `keep_set` guard invalidates any cache filtered under the old one.
