refactor: rename cli-v2 → cli, archive legacy cli, plus broker-side grants + auto-migrate

- apps/cli/ is now the canonical CLI (was apps/cli-v2/).
- apps/cli/ legacy v0 archived as branch 'legacy-cli-archive' and tag
  'cli-v0-legacy-final' before deletion; git history preserves it too.
- .github/workflows/release-cli.yml paths updated.
- pnpm-lock.yaml regenerated.

Broker-side peer-grant enforcement (spec: 2026-04-15-per-peer-capabilities):
- 0020_peer-grants.sql adds peer_grants jsonb + GIN index on mesh.member.
- handleSend in broker fetches recipient grant maps once per send, drops
  messages silently when sender lacks the required capability.
- POST /cli/mesh/:slug/grants to update from CLI; broker_messages_dropped_by_grant_total metric.
- CLI grant/revoke/block now mirror to broker via syncToBroker.

Auto-migrate on broker startup:
- apps/broker/src/migrate.ts runs drizzle migrate with pg_advisory_lock
  before the HTTP server binds. Exits non-zero on failure so Coolify
  healthcheck fails closed.
- Dockerfile copies packages/db/migrations into /app/migrations.
- postgres 3.4.5 added as direct broker dep.
