feat(safety): enhance claude-commit with mandatory review and safety features

Added comprehensive safety features to prevent accidental commits and ensure
user review of all generated commit messages:

Safety enhancements:
- Added mandatory review warning with clear visual indicators
- Implemented double confirmation for all commit operations
- Added option to regenerate commit message if not satisfied
- Shows edited message for review after modifications
- Added explicit "no auto-push" reminders after commits
- Created ~/.claude-commit.conf for safety preferences

Documentation updates:
- Updated CLAUDE.md with clear commit workflow for Claude Code
- Added safety features section to tool documentation
- Clarified that manual review is always required
- Documented the review-approve-commit-push workflow

These changes ensure users always have full control over commit messages
and prevent accidental commits or pushes without explicit approval.
