rzen df3eac9d5f Add a Live Activity for the running workout
A new iOS widget extension shows the active exercise, its phase, and the
work/rest countdown on the lock screen and in the Dynamic Island, driven
by the run flow's live frames so locking the phone mid-set keeps the
timer. The activity is seeded on open, refreshed on every page settle,
dismissed when the flow is left, and cleared on next launch if stranded.
Unifies the build-info stamping across all targets via a YAML anchor.

/// independently off the shared wall-clock anchors carried in each frame.
