 * Integration tests for the context_watch handler

 * These tests verify the handler's behavior through the actual tool interface,

 * - 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
