v0.3.12 (beta)

Fixed

• Inline reset respects offset: The inline period-boundary reset now correctly defers to the configured offset for cumulative sensors.
• Early reset skipping other periods: Fixed return → continue bug that skipped remaining periods in the loop.
• Delta entities deleted on reload: Delta sensor entities were incorrectly removed on every reload/restart.

Improved

• Extracted base class: _BaseMaxMinSensor eliminates ~200 lines of duplicated code (sensor.py 382 → 179 lines).
• Extracted shared methods: _compute_next_reset() and _schedule_single_reset() eliminate duplicated reset scheduling logic.
• Configured initial enforcement: Initial max/min values enforced as floor/ceiling after restore.
• Stale restore protection: Restored data without last_reset ignored when period already initialized.
