/**
 * sync-mirrors.mjs — per-mirror self-referencing install sources.
 *
 * Before pushing to each remote, rewrites the GitHub org inside the
 * install-source URLs of the docs (README*.md / INSTALL*.md) to that remote's
 * own organization, so every mirror's documentation points at itself:
 *   origin -> dsh-external, public -> lhh010, omdsh -> omdsh-dev.
 * The working tree keeps lhh010 (the public default) after the run.
 *
 * Usage: node sync-mirrors.mjs            (rewrite, commit, push each mirror)
 *        node sync-mirrors.mjs --no-push  (rewrite + commit only)
