/**
 * ADR-857 phase 5f-2: hook-events dialect is driven from the registry descriptor.
 *
 * Before this change, postToolEvent and preToolEvent were hardcoded strings
 * derived from runtime-name checks:
 *
 *   (runtime === 'gemini' || runtime === 'antigravity') ? 'AfterTool'  : 'PostToolUse'
 *   (runtime === 'gemini' || runtime === 'antigravity') ? 'BeforeTool' : 'PreToolUse'
 *
 * After phase 5f-2, both are driven by the registry descriptor's
 * `hookEvents` field: hookEvents === 'gemini' → AfterTool/BeforeTool;
 * any other value (or missing) → PostToolUse/PreToolUse.
 *
 * Equivalence (i.e. identical observable behaviour for all runtimes):
 *   hookEvents === 'gemini'  iff  runtime ∈ {gemini, antigravity}
 *
 * This suite asserts the equivalence and the registry-parity invariant:
 * any runtime whose descriptor carries hookEvents='gemini' gets the
 * AfterTool/BeforeTool dialect; all others get PostToolUse/PreToolUse.

/**
 * Enhancement #776: Adopt new Gemini hook events + detect hooksConfig.enabled:false.
 *
 * Gemini CLI exposes several hook events beyond BeforeTool/AfterTool that gsd
 * previously did not register.  This suite asserts that a Gemini install
 * registers the 3 new high-value events:
 *   - BeforeAgent  — fires before the agent plans (context headroom tracking)
 *   - AfterAgent   — fires after final response generation (context tracking)
 *   - BeforeModel  — fires before each LLM call (per-turn context awareness)
 *
 * All three are wired to gsd-context-monitor.js — the same hook used for
 * AfterTool — so context headroom warnings surface at these lifecycle moments.
 *
 * Also asserts:
 *   - Claude Code installs do NOT gain these Gemini-only events (strict scope guard).
 *   - Reinstalls are idempotent (no hook duplication).
 *   - Uninstall removes the new event registrations.
 *   - hooksConfig.enabled:false warning is emitted during a Gemini install.

 * Enhancement #788: Expand Qwen Code hook-event coverage.
 *
 * Qwen Code supports 15 hook events; gsd previously registered only
 * SessionStart and PostToolUse.  This suite asserts that a Qwen install
 * registers the 3 new high-value events:
 *   - SubagentStop  — subagent lifecycle finalisation (context tracking)
 *   - Stop          — model stop / final-response hook (context tracking)
 *   - PreCompact    — pre-compaction awareness (context tracking)
 *
 * All three are wired to gsd-context-monitor.js — the same hook used for
 * PostToolUse — so context headroom warnings surface at these moments too.
 *
 * Note: UserPromptSubmit is NOT wired — gsd-prompt-guard exits unless
 * tool_name is Write|Edit (PreToolUse shape), so it would be a no-op for
 * the UserPromptSubmit payload.  Deferred to a follow-on issue.
 *
 * Also asserts the inverse: Claude Code installs do NOT gain these events
 * (strict isQwen scope guard).

 *   1. Claude Code installs register SubagentStop, Stop, and PreCompact, each

 *   2. Claude Code installs register a FileChanged hook for .planning/config.json
 *      wired to gsd-config-reload.js (new hook; hot-reloads gsd config).
 *   3. All four registrations are idempotent (reinstall does not duplicate).
 *   4. Uninstall removes all four event registrations.
 *   5. The gsd-config-reload.js hook script exists in hooks/ and has the
 *      expected structure (reads on stdin, emits additionalContext or exits 0).
 *   6. The hooks/hooks.json plugin manifest includes the new events.
