/**
 * Tests for the CMS publish flow (MITHOME-60):
 *
 * Unit (scripts/cms-publish.js):
 *   - command shape: marker echo, conditional commit, rebase-abort fallback
 *   - result interpretation: marker → no_changes; no marker → ok; error → error
 *
 * Integration (real server + throwaway git repos):
 *   1. publish with no changes   → ok, "Nincs új változtatás.", NO deploy
 *   2. publish with real changes  → ok, commit pushed, deploy ran
 *   3. publish with rebase conflict → error reported, rebase aborted (repo not
 *      left mid-rebase), push never happened, no deploy
