chore(release): v1.28.55 — the Today view comes to life

Bundles three daily-loop slices onto the Today view:
- Coach check-in: a due plan review surfaces as a calm Today card with
  keep/adjust/let-go, wired to the existing plan lifecycle; silence never
  changes a plan.
- Morning freshness: the sleep-dependent parts of the digest and score refresh
  the moment last night's sleep arrives (a debounced, timezone-correct per-user
  job across the Withings, WHOOP and Apple transports), with an honest
  provisional state until then. Adds migration 0244 (a per-user refresh marker).
- Daily push: an opt-in, once-a-day morning notification carrying the day's
  read, off by default, riding the existing dispatch cascade — a calm note,
  never an alert.

All read the overnight digest; nothing generates on open.
