fix: optimize agent compiler and complete handler cleanup

- Add deployment-aware handler generation (filters web-only/ide-only commands)
- Remove unused run-workflow handler type (ghost handler cleanup)
- Implement missing validate-workflow and data handler generation
- Update schema validation to support exactly 6 active handler types
- Clean up activation templates and web bundler logic
- Prevent generation of unused handler instructions for better performance
- All 62 tests pass with backward compatibility maintained
