Publish consistent measured drive activity (#89)
Repair the collection-to-display path so each successful acquisition publishes correct read/write deltas through the observation store and visible dashboard. Fixes: - derive.py: accumulate bytes_read_delta on same-hour hour_observation merge (was silently dropped) - collector.py: rebuild day_aggregates from hour observations after each collection run (previously only populated for cross-hour intervals) - day_aggregate.py: add persist_day_aggregate upsert helper - tui.py: query and display both read and write deltas in daily and hourly readouts, constrained summaries, and graph data queries Tests: - Add 14 integration tests (test_measured_activity.py) exercising the full collector→store→reader→display path with real fixtures and injected time - Update constrained-layout assertion to match new W/R format Closes #89
