Fix agent loading and categorization issues

- Fixed YAML frontmatter errors in all agent files causing loading failures
- Added proper category fields to all 16 agents for correct classification
- Standardized agent names to match filenames for consistency
- Updated TODO.md to reflect completed agent system fixes
- Enhanced agents-install-cli make target with pip upgrade and user guidance

All agents now load properly without warnings and display in correct categories:
- Documentation (1), Code Quality (4), Project Management (4)
- Development Process (3), Infrastructure (1), Testing (3)
