feat(cli): add interactive setup wizard with Antigravity support

- Add @clack/prompts for modern interactive CLI experience
- `distill-mcp setup` now launches an interactive wizard by default
- Add Antigravity (Google) IDE support alongside Claude Code, Cursor, Windsurf
- Pre-select detected IDEs in the wizard
- Keep backward compatibility with flags (--claude, --cursor, --windsurf, --antigravity)
- Update documentation (EN + FR) with new setup flow
