feat(git): implement debug code prevention system with deliberate installation

Implements comprehensive pre-commit hook system to prevent debug code from
reaching protected branches while maintaining developer choice.

- Hooks stored in scripts/git-hooks/ (not in .git tree)
- Deliberate installation required - no forced behavior
- Automated installation script for team members
- Comprehensive testing
- Branch-aware execution (protected vs feature branches)
- Configurable patterns and protected branch list

Philosophy: Each developer chooses whether to use the hook, ensuring
team flexibility while providing powerful debug code prevention tools.
