/**
 * install-guidance migration (guidance-layers-never-resolve/AC-2).
 *
 * Projects initialized before guidance installation existed have no
 * `.aidlc/guidance/` at all — or only the layers they authored themselves — so
 * every `{{guidance:<layer>}}` placeholder in their skills has nothing to resolve
 * against. This migration installs the layers the content package ships.
 *
 * Safe tier: it only adds files that are absent and appends entries to
 * `index.yaml`. A layer whose body has been edited locally is reported and left
 * alone, so applying this can never overwrite project-authored guidance.
 *
 * Note this repairs the *layers*; the placeholders in already-emitted skill
 * bodies are rewritten by the skill refresh in `aidlc update`.
