/**
 * adapters/vscode-copilot/hooks — VS Code Copilot hook definitions and matchers.
 *
 * Defines the hook types, matchers, and registration format specific to
 * VS Code Copilot's hook system. This module is used by:
 *   - CLI setup/upgrade commands (to configure hooks)
 *   - Doctor command (to validate hook configuration)
 *   - Hook config generation
 *
 * VS Code Copilot hook system reference:
 *   - Hooks are registered in .github/hooks/*.json
 *   - Hook names: PreToolUse, PostToolUse, PreCompact, SessionStart (PascalCase)
 *   - Additional hooks: Stop, SubagentStart, SubagentStop (unique to VS Code)
 *   - CRITICAL: matchers are parsed but IGNORED (all hooks fire on all tools)
 *   - Input: JSON on stdin
 *   - Output: JSON on stdout (or empty for passthrough)
 *   - Preview status — API may change
