* feat: add Antigravity runtime support
Add full installation support for the Antigravity AI agent, bringing
get-shit-done capabilities to the new runtime alongside Claude Code,
OpenCode, Gemini, Codex, and Copilot.
- New runtime installation capability in bin/install.js
- Commands natively copied to the unified skills directory
- New test integration suite: tests/antigravity-install.test.cjs
- Refactored copy utility to accommodate Antigravity syntax
- Documentation added into README.md

* fix: add missing processAttribution call in copyCommandsAsAntigravitySkills
Antigravity SKILL.md files were written without commit attribution metadata,
inconsistent with the Copilot equivalent (copyCommandsAsCopilotSkills) which
calls processAttribution on each skill's content before writing it.
