The TKG guard was checking if nodes exist before spawning TKG build.
This caused a deadlock when:
1. TKG spawns (async)
2. ingestion_complete checks → false (nodes not yet created)
3. Returns Ok(false), job stays running
4. Next poll: guard checks nodes → no nodes yet (TKG still running)
5. Skips TKG → deadlock!
Since build_tkg uses ON CONFLICT (idempotent), it's safe to call
multiple times. Removed the guard to fix the deadlock.
