feat(skills): rename kvb-org-split to kvb-org-swarm, add kvb-org-unify

kvb-org-swarm keeps agent work in its own worktree until it meets 90/5; kvb-org-unify brings the swarm's branches back together. Every skill that named kvb-org-split now names kvb-org-swarm. Cost 111 % accepted by the operator on 2026-11-11.
