- Raise target humidity setpoints from 40% to 55% with a 2% hysteresis shut-off
- Eliminate 9999-min unlimited runtime bypass and strictly cap bursts at 35 min
- Rebalance duty cycle to 1:1 ratio (35 min run, 35 min cooldown rest)
- Implement Shelly internal RTC time-of-day check to restrict routine drying to 02:00-07:00
- Add delta-T guard requiring spread >= 3.5°C and max 20 min bursts when outside is >8°C colder
- Update AGENTS.md documentation to reflect optimized gates and thresholds
