felixxia-oai 2f1cc59790 Add channel upserts to message boards (#56494) ...

## What changed

Add an `upsert_channel` API and selectable tool to create a channel or replace only its description. Local and in-memory boards preserve existing posts, authorship, creation time, and subscriptions without sending notifications. Updating an existing channel does not require the host clock.

Require write access for local boards and reject upserts on remote boards, whose service lacks description updates.

## Testing

Add coverage for both local and in-memory upserts, argument validation, mutation budgets, metadata preservation, and clock failures. Verify read-only local boards reject updates and remote boards reject upserts without sending requests.
