feat(copilot): add dummy agent generator for testing

Add optional dummy agent generator that returns mock responses matching
the expected format from the external Agent Generator service.

Enable via AGENTGENERATOR_USE_DUMMY=true in settings.

Changes:
- Add agentgenerator_use_dummy setting to settings.py (default: false)
- Create dummy.py with mock implementations of all service functions
- Modify service.py to route to dummy when enabled
- Add startup warning when dummy mode is active

This enables local CoPilot testing without needing the external
Agent Generator service running.

+
