feat: add Google Antigravity IDE support with global install

- Add Antigravity to IDE configurations in bin/install.js
- Global install path: ~/.gemini/GEMINI.md (works across all projects)
- Cross-platform home directory expansion (os.homedir())
- Add --antigravity flag support
- Update package.json keywords
- Maintain backward compatibility with all existing IDEs
