Reset countdown at midnight after overtime - #37
Merged
Conversation
Leaving the machine on past midnight after overtime parked the daemon in :done, so the next day's shutdown was never enforced. Arm a midnight timer that resets to severance mode and waiting, reschedules the countdown, and re-arms itself.

The reset timer waits monotonic milliseconds, but the interval to the next midnight is wall-clock, so a DST transition fires it up to an hour off. Track the session's local date and only roll over once the date has actually advanced; an early fire just re-arms, which re-reads the clock and self-corrects.
The day-rollover decision lived inside the GenServer callback and read the clock through the now_fn injection, forcing tests to override it. Move it into a pure reset_state/2 that takes the current day as an argument, so the rollover and DST early-fire cases test directly without dependency injection.
…me is a single-day opt-out and the next day's shutdown is enforced again
