/**
 * pi-skills-mention — Codex-style `$skill-name` mentions for pi.
 *
 * Adds two things to pi:
 *
 *  1. **Runtime skill loading.** Any `$skill-name` written anywhere in a
 *     prompt (not just at the start) loads that skill's full instructions
 *     before the agent runs. You can mention many skills in one message, mix
 *     them with ordinary text, and re-mention in later turns:
 *
 *         $code-review 与 $humanize 帮我审查今天下午改的 auth 模块，并把结论润色成人话。
 *
 *     The prompt itself is **never rewritten**: pi stores and displays exactly
 *     what you typed (with the `$skill` mentions), so `/fuck`-style recovery,
 *     rewind and re-editing always work on your original text. The skill
 *     contents are injected as a separate custom message right before the
 *     agent starts, and the TUI renders a compact "loaded skills" line for it
 *     (`ctrl+o` expands the full contents).
 *
 *  2. **TUI autocompletion.** Type `$` in the input editor and a live list of
 *     mentionable skills appears, filtered as you type — Codex's `$` feel.
 *
 * Escape hatch: `$$name` stays a literal `$name` (never loaded).
