- Redesign the watch app into an active-workout runner: a root gate shows the in-progress workout's exercises or prompts to start one on iPhone, and each exercise runs as a horizontally-paged HIIT cycle (count-up work, count-down rest with final-three-second haptics + auto-advance, One More / Done on the last set). Replaces the old history list. - Add a configurable rest-between-sets duration in iPhone Settings (default 45s), synced to the watch over WatchConnectivity. - Launch the watch app into the session when a workout starts on the phone via HealthKit (startWatchApp); the watch runs an HKWorkoutSession for foreground runtime and ends it when the workout finishes. Adds the HealthKit entitlement + Health usage strings on both targets and WKBackgroundModes on the watch. Claude-Session: https://claude.ai/code/session_018gg69MaUetDNzWzBXisfMV
