- WebSocket broadcasts: Next.js tRPC router now routes broadcasts via
POST /internal/broadcast on the Bun ws-server process, which holds
the actual client connections. Broadcasts were previously silently
dropped due to the split singleton across processes.
- ws-server stubs: request_trial_status and request_trial_events now
use the real async DB methods instead of the stub getTrialStatusSync/
getTrialEventsSync that always returned null/[].
- Duplicate branch case: removed the unreachable second case "branch"
block in executeAction switch; server-side branching is a pass-through
since routing is client-orchestrated.
