/**
 * `harn doctor`: runtime + dependency check.

 * Walks through every dependency harnery touches and reports presence,

 *
 *   ✓ ok: dep is present and recent enough
 *   ⚠ warn: optional dep missing (feature degrades)
 *   ✗ fail: required dep missing (commands will throw)
 *
 * Exits 0 unless a required dep is missing.
