Heat skip: if Warsaw temperature >= 32°C at locker startup, a fullscreen dark-themed dialog asks the user to confirm skipping. Temperature is always fetched from wttr.in automatically (user cannot self-report). Fail-closed: API unavailable → no dialog, normal lock. Placed before skip-credit consumption so credits are preserved when heat skip is used instead. Logs a heat_skip entry (with temperature) to workout_log.json; does not count toward weekly minimum. Visible in --status as "Heat skips (month)". Early-bird gap fix: the re-check timer now fires at both 08:30 (normal 5:00–8:30 window) and 09:05 (extended 5:00–9:00 window earned by 5+ workout weeks). Previously the 08:30 run would see the window still active on extended weeks and never re-check after 9:00.
