/**
 * `aidlc hook` — lifecycle hooks for agent harnesses.
 *
 * Two subcommands run inside a harness hook and two install them:
 *
 * - `session-start` prints the claimed instance, its phase and its next step,
 *   for a `SessionStart` hook to add to the agent's context after startup,
 *   resume, `/clear` or compaction.
 * - `guard` answers a Claude Code `PreToolUse` call with `ask` while the claimed
 *   instance is being planned, and with silence otherwise.
 * - `install` / `remove` write those into `.claude/settings.json`, and the
 *   session-start hook into `.codex/hooks.json` only when asked by name.
 *
 * The two hook-mode subcommands exit 0 on every path and print nothing when they
 * have nothing to say: a hook that fails must never stop a session starting or a
 * file being edited (hooks-carry-lifecycle-state/AC-7, AC-12, AC-13).
 *
 * Design: design.md C5
 *
 * @module
