/**
 * 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)
 *   - 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

/**
 * Build the hook command string for a given hook type.
 *
 * Always emits the CLI dispatcher form
 * (`context-mode hook vscode-copilot <event>`) — the `pluginRoot` argument
 * is accepted for API compatibility but intentionally ignored.
 *
 * Why the dispatcher form is mandatory here (Issue #613 — Tier C contract):
 *   `.github/hooks/context-mode.json` is a **workspace-committed** file
 *   (upstream: refs/platforms/vscode-copilot/assets/prompts/skills/
 *   agent-customization/references/hooks.md line 7 — "Workspace
 *   (team-shared)"). It lands in every teammate's `git status`. Embedding
 *   `process.execPath` or any absolute pluginRoot path here:
 *     - Leaks PII (username, `C:/Users/<user>/...` paths).
 *     - Breaks cross-machine portability (fnm/nvm/volta/brew shims are
 *       per-shell-session ephemeral; the path goes stale immediately on
 *       Windows + fnm).
 *
 * Commit `f5c9d02` (2026-03-06) added an absolute-path branch when a
 * pluginRoot was passed. It solved a real PATH-availability bug on
 * Brew/nvm setups by going too far — the CLI then always passes
 * pluginRoot, so the portable form became unreachable in production
 * and every `/ctx-upgrade` baked a non-portable command into the
 * committed config. This reverts to the pre-`f5c9d02` shape.
 *
 * For users without a global install, the recovery path is the same as
 * every other CLI-dispatcher adapter (cursor, codex):
 *   `npm install -g context-mode`
