Replaced broad try-catch blocks with targeted error handling that only
catches expected business logic errors (CommandProcessingError subclasses).
System errors (OOM, DB failures, network issues) now propagate correctly
for proper debugging and monitoring.
Changes:
- Created CommandProcessingError hierarchy for business logic errors
- UnknownCommandTypeError for invalid command types
- AgentCommandError for orchestrator communication failures
- InvalidCommandPayloadError for payload validation
- Updated command.service.ts to only catch CommandProcessingError
- Updated federation-agent.service.ts to throw appropriate error types
- Added comprehensive tests for both business and system error scenarios
- System errors now include structured logging with context
- All 286 federation tests pass
Impact:
- Debugging is now possible for system failures
- System errors properly trigger monitoring/alerting
- Business logic errors handled gracefully with error responses
- No more masking of critical issues like OOM or DB failures
Fixes#281
