Subject: [PATCH 1/2] perf(medications): index the dashboard meds-today read
 shapes

Two additive indexes on medication_intake_events: (user_id, scheduled_for)
for the sibling reads that filter without medication_id, and
(user_id, medication_id, taken_at) for the per-medication last-taken
group-by that scanned the whole intake history on every dashboard load.
Additive migration 0253, no data change, no behaviour change.

 ## [Unreleased]
 
+## [1.30.12] — 2026-07-18
+
+Faster medication reads.
+
+- **The dashboard's medication section stays fast as your log grows.** Its reads now use dedicated indexes instead of scanning the full intake history on every load, so a long history no longer slows down the daily view.
+
+No breaking changes.
+
 ## [1.30.11] — 2026-07-18
 
 Native single sign-on.
