Sibling Sync
Bilateral reconciliation of SYNERGY-*.md and UPSTREAM-*.md files between
this project and its sibling vp-* projects. Read-only by default — surfaces
drift, reciprocal gaps, stale-aligned rows, and status drift across sides
without mutating anything. The opt-in --auto-reciprocate flag writes
reciprocal entries to the sibling's SYNERGY file via per-entry confirmation.
Companion to /vendor-sync (which handles upstream → project drift); this
skill handles peer-to-peer drift
