ops: right-size relay cluster resources
- jetstream: use internal service URL (ws://relay:2470) instead of
public ingress (wss://relay.waow.tech) — fixes websocket handshake
failures causing 30+ crash-loop restarts
- relay: lower memory limit 8Gi → 5Gi (actual ~4.2 GiB w/ 500K cache)
- collectiondir: bump memory limit 2Gi → 2560Mi (pebble index at
1.45 GiB and growing)
- reconnect cronjob: reduce job history 3 → 1
