Kenny Yi 2326a3f74b Scope model catalogs and caches by thread originator (#56284) ...

## What changed

Select an originator-specific models manager before resolving thread model metadata. Supported originators send their own `originator` header and use separate in-memory catalogs and disk caches, so each thread receives the corresponding model instructions and tools.

Reuse managers for repeated originators and share the API-key model discovery setting across them. Unsupported originators retain the default manager and catalog.

## Testing

Add coverage for originator headers, concurrent catalog isolation, cache reuse across restarts, shared discovery policy, and the instructions and tools sent in actual turns.
