Module sync 

Catalog sync tooling — merge models.dev into the embedded catalog. Catalog sync engine — merge a live models.dev payload into the embedded catalog.

The catalog is split into two concerns:

• Connection metadata (auth, base URL, install-wizard text, model tiers): llm-kernel-specific, always kept from the catalog.
• Model data (pricing, limits, modalities, capabilities): the source of truth is models.dev. merge_catalog refreshes it for every provider that maps to models.dev (crate::provider::mapping); providers with no upstream counterpart are left untouched.

merge_catalog is pure (no I/O) so it is unit-testable without network.
