refactor: replace empty cc_agents file with agent templates directory

- Remove empty cc_agents file that was previously added
- Add cc_agents directory containing three agent configuration templates:
  - git-commit-bot: Automated git commit message generation
  - security-scanner: SAST security vulnerability detection
  - unit-tests-bot: Comprehensive unit test generation
- Each agent includes detailed system prompts and workflow configurations
- Templates are exported in .claudia.json format for easy import

This change provides ready-to-use agent templates for common development workflows.
