- Replace multiprocessing/threading with single asyncio task per agent
- Add task cancellation: new request cancels previous for same agent
- Add per-agent state isolation via ContextVar for Terminal, Browser, Python managers
- Add posthog telemetry for tool execution errors (timeout, http, sandbox)
- Fix proxy manager singleton pattern
- Increase client timeout buffer over server timeout
- Add context.py to Dockerfile
- Add ThreadPoolExecutor in agent_worker for parallel request execution
- Add request_id correlation to prevent response mismatch between concurrent requests
- Add background listener thread per agent to dispatch responses to correct futures
- Add --timeout argument for hard request timeout (default: 120s from config)
- Remove signal handlers from terminal_manager, python_manager, tab_manager (use atexit only)
- Replace SIGALRM timeout in python_instance with threading-based timeout
This fixes requests getting queued behind slow operations and timeouts.
