feat: Add -C parameter support for directory context in CLI tools

- Add -C parameter to gemini-wrapper for directory change before analysis
- Update intelligent-tools-strategy.md to use -C (uppercase) consistently
- Replace cd [directory] functionality with -C parameter throughout docs
- Add directory context examples for both Gemini and Codex tools
- Enhance context optimization strategy with -C parameter usage
- Test confirms -C parameter works correctly with token analysis in target directory
