Commit Message

feat(chart): SSE-friendly rolling update defaults for the hub Deployment

Hardcode three fields on the Deployment that make a rolling update
non-disruptive for hubs carrying live SSE subscribers:

- strategy.rollingUpdate.maxSurge=1, maxUnavailable=0 — one pod at a
  time, no capacity drop, so each batch of reconnects hits separately
  from the previous batch.
- minReadySeconds: 30 — a newly-Ready pod gets 30s of quiet time to
  reach steady state (bolt DB warm-up, or the transport backend loops
  of the Enterprise transports) before the next rotation fires, so
  load doesn't stack on the transport.
- terminationGracePeriodSeconds: 660 — Mercure's DefaultWriteTimeout
  (600s) plus a 60s margin, so the graceful-shutdown drain (introduced
  in the hub) has time to let SSE handlers close at writeTimeout's own
  pace instead of being SIGKILLed mid-drain.

All three are chart-internal: no new values.yaml surface. Users who
override writeTimeout via the write_timeout Caddyfile directive or
MERCURE_WRITE_TIMEOUT env var must bump terminationGracePeriodSeconds
accordingly — documented inline in the template comment.
