feat: add Antigravity CLI support, --list flag, and skill descriptions

- Replace Gemini CLI with Antigravity CLI throughout (--gemini kept as
  hidden fallback flag; GEMINI_SKILLS_DIR honoured as legacy env var)
- Default install dir updated to ~/.gemini/antigravity-cli/skills
- Add ANTIGRAVITY_SKILLS_DIR env var with GEMINI_SKILLS_DIR fallback
- Add -l/--list flag: lists available skills with one-line descriptions
- Add descriptions.json mapping skill names to short descriptions;
  fetch_descriptions() prefers a local copy when running from a clone,
  falls back to remote URL for curl-pipe installs
- Document ship-it skill in README (was missing since its addition)
- Fix Manual Install cd path: claude-skills → ai-skills

+**Purpose:** Run a comprehensive pre-flight audit and publish changes to a new PR in a single command.
+
+Two sequential phases — Phase 2 is blocked until Phase 1 succeeds:
+
+1. **Documentation Sync & Code Audit** — acts as `/readme-sync-audit`: scans all file changes since the last README edit, updates the README to match the current codebase, and audits code files for syntax errors or regressions. **Halts the entire workflow** if any breaking issue is found.
+2. **Git Publish Workflow** — acts as `/git-publish-workflow`: creates a descriptively named branch, commits all pending changes (including the README updates from Phase 1), pushes to the remote, and opens a Pull Request against `main`.
+
+**Use when:** you say "Ship this," "Publish my changes," or invoke `/ship-it`.
