felixxia-oai d6ea5991e7 Add metrics for extension-rendered skill catalogs (#35597) ...

## What changed

- Add an optional `ExtensionMetrics` capability to thread, turn-input, and world-state contributors, backed by session telemetry in the host.
- Record skill counts, omissions, and truncated description characters for extension-rendered catalogs, tagged by the catalog surface.
- Preserve host session attribution on extension metrics, including the effective model for each turn, and prevent extension tags from overriding host metadata.
- Avoid duplicate host-catalog samples by recording world-state metrics only when the section is published or changes.

## Testing

- Cover metric values and surface tags, session metadata preservation, turn-level model changes, and host world-state publication behavior.
