Finish v1 → v2 migration

bash migrate-v2.sh already ran the deterministic migration. It handled:

• .env keys merged
• v2 DB seeded (agent_groups, messaging_groups, wiring)
• Group folders copied (v1 CLAUDE.md → v2 CLAUDE.local.md)
• Session data copied with conversation continuity (incl. Claude Code memory + JSONL transcripts)
• Scheduled tasks ported
• Channel code installed and auth state copied (incl. WhatsApp Baileys keystore)
• WhatsApp LIDs resolved from store/auth and aliased into messaging_groups
• Container skills copied
• Container image built

Your job is the parts that need human judgment: triage failed steps, seed the owner, run the shared-memory migration, reconcile configs, and port fork customizations.

Read logs/setup-migration/handoff.json first — it has overall_status, per-step results in steps, and a followups list.
