Fixes deadlock issues in node manager that cause operations to become unresponsive.

Changes in Rust implementation:

  • Add timeout handling for process spawn operations (30 seconds)
  • Add timeout handling for health check operations
  • Implement proper cleanup in error cases
  • Improve event emission and error handling
  • Add proper process cleanup on timeout or error
  • Minimize lock holding durations

These changes prevent deadlocks during:

  • Node status queries
  • URL fetching
  • Start/stop operations
