What’s new

• src/mcp/tools/withErrorHandler.ts, Reusable error boundary for MCP tool handlers
• 39 new MCP backend tests (75 total), webhooks, worker management, monitoring, batch operations, heartbeat, progress, full lifecycle

Bugfixes

• MCP error handling: All 66 tool handlers now wrapped with withErrorHandler that catches backend exceptions and returns structured { error: "message" } responses with isError: true instead of raw stack traces
• MCP TCP connection: createBackend() is now async and properly awaits TCP connection. Previously used fire-and-forget (void backend.connect()) which silently swallowed connection failures
• MCP not-found responses: bunqueue_get_job, bunqueue_get_job_by_custom_id, bunqueue_get_progress, and bunqueue_get_cron now return isError: true when resource is not found
