chore(curation): automated catalog sync 2026-07-07

[bitrouter-automation]

Automated catalog sync — as-of 2026-07-07 — auto_sync providers only.
Keyless model-catalog update: attaches the canonical models each auto_sync=models_dev provider serves, per models.dev. New-model onboarding and deprecation (Artificial Analysis) are NOT run automatically — a maintainer runs curate apply / resolve on demand. Review the diff and merge.

Catalog sync (keyless)

$ bun run scripts/curate.ts sync --write
