Fixes

1. Coalesced concurrent fetchAllData requests

   • DataStore now queues completion handlers while a fetch is active to prevent overlapping network fan-out and state churn.

2. Reduced AVPlayer churn in iOS workout detail

   • Reuses current player for same URL by seeking to start instead of recreating AVPlayer each time exercise/video updates.

3. Reduced AVPlayer churn in iOS exercise preview sheet

   • Added preview URL tracking; same URL now replays without allocating a new player.

4. Reduced AVPlayer churn in tvOS content loop

   • Same URL replay now seeks/replays existing player rather than recreating.

5. Capped queued watch messages on iOS bridge

   • Added queue cap to prevent unbounded growth while watch is disconnected.

6. Added queue fallback for send failures

   • Failed reachable send now re-queues payload for later delivery.

7. Improved timer power behavior

   • Added timer tolerance to workout/exercise timers.

8. Fixed watch heart-rate loop early-return behavior

   • Non-heart sample types now continue instead of exiting handler early.

Validation

• Smoke suite passed:
  • token scan
  • SharedCore tests
  • iOS/watchOS/tvOS builds
