/**
 * Regression Tests: Antigravity setup + hook adapter
 *
 * Covers:
 * - setupAntigravity: detection of ~/.gemini/antigravity, MCP write, preserve
 *   existing keys, corrupt-file handling, skips when not installed.
 * - installAntigravityHooks: writes ~/.gemini/settings.json with an
 *   AfterTool entry under the canonical Gemini CLI / Antigravity 2.0 layout
 *   (https://geminicli.com/docs/hooks/reference/); copies the adapter and
 *   lock helpers to ~/.gemini/config/hooks/gitnexus/; idempotent across
 *   re-runs; preserves existing user hooks ("polite neighbor").
 * - installAntigravitySkills: lays out skills under ~/.gemini/antigravity/skills/.
 * - hook adapter: AfterTool emits `{hookSpecificOutput.additionalContext}`
 *   with graph context after search-like tools; emits a stale-index hint
 *   after a successful `git commit/merge/rebase/cherry-pick/pull`; ignores
 *   unrelated tools silently.
