Addresses merge-time issues and gaps from the realtime app split:
- Retarget stale vi.mock paths to @sim/workflow-persistence/subblocks
- Restore README branding, fix AGENTS.md script reference
- Restore TSDoc on workflow-persistence subblocks helpers
- Use toError() from @sim/utils/errors in save.ts
- Add vitest config + local mocks so @sim/audit tests run standalone
- Move socket.io-client to devDependencies in apps/realtime
- Add missing package COPY steps to docker/app.Dockerfile
- Add check:boundaries/check:realtime-prune scripts and wire into CI
