"""Merge skill registry and actor/automation heads.

After rebasing feature/m3-skill-registry onto the session-persistence
chain, c0_001_skill_registry still pointed at 71cd40eb661f while the
main chain had advanced through a7_002 -> c3_001 -> a6_002.  This
no-op merge migration resolves the two heads into one.
