Hold a numeric count on the watch's Always-On timer

In the Always-On / wrist-down state, watchOS throttles the system timer
text and collapses sub-minute values to a relative "< 1 min", which
overflows the 50pt counter font and truncates with an ellipsis.

Gate PhaseTimerLayout on isLuminanceReduced: keep the live system timer
while active, but render our own held "~m:ss" snapshot from the wall-clock
anchors in Always-On — so the count stays numeric and on-screen. Timing is
unaffected (haptics/auto-advance still run off the anchor, not the text).

+During an Apple Watch workout, lowering your wrist now keeps the work or rest timer showing its most recent count (marked with a ~) instead of a cut-off "less than a minute".
+
 Add a Workouts complication to your Apple Watch face — tap it to open the app straight from any watch face.
 
 Prop your iPhone up during an Apple Watch workout and it now runs the same live flow side by side — Ready → work/rest → Finish with running timers — and you can drive from either device: swipe ahead, finish a set, or add one on whichever is closer, and the other follows along. Automatic moves, like a rest timer running out, advance both devices on their own.
