/**
 * Tests for marker-driven profile re-application on `gsd update` (Deviation 2).
 *
 * Verifies:
 *   1. resolveEffectiveProfile returns the marker's profile when no explicit flag given.
 *   2. Explicit --profile flag overrides the marker.
 *   3. Multi-runtime marker disagreement resolves to the most-restrictive profile.
 *   4. Missing marker falls back to 'full'.
 *   5. stageSkillsForProfile is called with the resolved profile (not 'full') on updates.
