v1.4.35 — persistent measurement rollups + partial read-swap

Foundation release for the persistent measurement_rollups cache tier.
Adds the additive table + enum, populates it from every measurement
write hook, lands the Apple-Health-import end-of-job backfill, and
ships the parity-checked read-swap on two reader surfaces.

The comprehensive insights aggregator and the slim analytics
summaries slice now source count / min / max / mean per type from the
DAY rollup buckets via aggregateBuckets, plus the comprehensive
dailyByType correlation feed straight from the bucket means. Slope /
R² / standard deviation / anomaly counts stay on live SQL — they do
not compose across DAY buckets. A defensive parity check against the
live aggregate's COUNT(*) falls back to live SQL when divergence is
detected.

Includes the new scripts/backfill-rollups.ts CLI for the one-shot
fold of historical measurements into all four granularities.

Tests: 4280 unit + 228 integration. tsc + lint clean. Migration
0067_v1434_measurement_rollups is idempotent under re-run.
