Release v4.1.0 - Graceful session cleanup and MCP search server restoration

### Changed
- Graceful session cleanup: Cleanup hook now marks sessions as completed instead of sending DELETE requests to worker
- Natural worker shutdown: Workers now finish pending operations (like summary generation) before terminating
- Restored MCP search server: Re-enabled full-text search capabilities from backup

### Fixed
- Session summaries no longer interrupted by aggressive cleanup during session end
- Workers can now complete final operations before shutdown

### Dependencies
- Updated @anthropic-ai/claude-agent-sdk to ^0.1.23
- Added @modelcontextprotocol/sdk ^1.20.1
- Added zod-to-json-schema ^3.24.6
