workout_app: run the break countdown in a foreground service with notifications
The between-set break never finished once the phone's screen was off. Three
independent causes (worked through on-device on 2026-09-12; left
uncommitted awaiting the go-ahead, committed here as-is plus one pin bump):

1. The countdown was not wall-clock: `_breakRemaining--` on a
   Timer.periodic, which Android throttles and Doze suspends in a
   backgrounded isolate, so the counter stalled and _onBreakFinished()
   never fired. Now a BreakClock deadline on the wall clock.
2. An expired break was silently dropped on restore (`if (remaining > 0)`
   only) — now cued and logged.
3. No notification infrastructure at all: no package, no
   POST_NOTIFICATIONS / FOREGROUND_SERVICE / WAKE_LOCK.

Now: flutter_foreground_task runs the countdown in a service isolate that
survives BACK and the screen lock; flutter_local_notifications shows an
ongoing "Workout A · break m:ss / Next: …" notification with −1 rep / Done
actions and a "Break over" alert on its own channel (raw break_end sound,
vibration). Button presses go through a persisted BreakIntent queue the
screen drains on resume, so a press with the app killed is not lost.
Finish and Reset stop the service; a startup reaper handles the crash case.

Verified on the phone with the screen off and locked: service alive and
ticking while Dozing, both notifications on the lock screen, channel
importance 5 with the break_end sound. Not verifiable from adb (receiver is
RECEIVER_NOT_EXPORTED): an actual action-button tap, and a true recents
swipe — see stronglift_replacement/TODO-workout-app-v2.md.

Also fixed en route: the break-end sound had never played in any widget
test (AssetSource needs path_provider, which nothing faked, and the failure
was swallowed by catchError); the queue's prune wrote back a stale list.

This commit additionally:
- takes the freshness gate's bump flutter_local_notifications 22.3.1;
- restores web/package.json to HEAD (the tree held a stale pre-bump copy);
- gives scripts/check_flutter_coverage.sh a FLUTTER_TEST_CONCURRENCY knob:
  the default one-isolate-per-core run peaks over 4 GiB and is OOM-killed
  under the resource cap. Default behaviour unchanged.

Gate: flutter analyze clean, 511 tests, 3187/3187 lines (100%), pre-commit
green. Not re-installed on the phone for the 22.3.1 pin: no device attached
at commit time.
