Add query_local_day_history() with evidence-limit metadata to local_day.py,
including LocalDayHistoryEntry dataclass that annotates each summary with
detail_available and derived_from_surviving flags. Document the 14-day
detail vs indefinite-summary retention policy in both local_day.py and
pruning.py.
Fix query_local_day_summary() to convert SQLite integer booleans to Python
bool, and add deduplication guard to the midnight-spanning hour logic in
derive_local_day_summary().
Add 17 lifecycle tests covering all acceptance criteria:
- AC1: Summaries survive sample pruning, evidence limits visible
- AC2: Boundary anchors preserved before pruning
- AC3: Timezone survives system-timezone change
- AC4: Legacy UTC summaries labelled incomplete
- AC5: Idempotent pruning and repair
- AC6: Volume conservation (no double counting)
- AC7: Real temporary stores
- AC8: User-visible transition from recent to aged
- AC9: Retention policy documented
All 775 tests pass.
Add local-day activity summaries derived from UTC hour observations using
the system timezone, with durable storage in a new local_days table.
The collector derives local-day read/write totals after UTC aggregation;
the TUI displays them with timezone, completeness state, and coverage.
Schema: bump SCHEMA_VERSION to 3, add local_days table (migration 2→3
is pure addition, idempotent, preserves newer-schema refusal).
