/**
 * Subagents staleness — one directory per subagent (must contain AGENT.md),
 * first-wins across project > user > system > extras.
 *
 * Bug-fixed from v1: the old manifest derived its name list from
 * `listInstalledSubagents()` which only walks user + system. With project
 * subagents in `available.subagents`, the name-set diff always flipped to
 * "stale". This checker walks all four layers consistently.
