* Integration tests for the context_watch handler
*
* These tests verify the handler's behavior through the actual tool interface,
* ensuring we test:
* - Watcher creation with various filters
* - Change detection (CREATE, UPDATE, DELETE)
* - Polling mechanism with sequence numbers
* - Watcher lifecycle (create, poll, expire, stop)
* - Privacy boundaries and session isolation
* - Performance with many watchers and large changesets
