Add HIIT watch runner, rest-time setting, and HealthKit watch auto-launch

- 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

+/// Root of the watch app. The watch only runs the workout that's currently active
+/// on the phone — there's no history browsing here. The "active" workout is the most
+/// recent cached one that isn't finished (`notStarted` or `inProgress`); a workout is
+/// created on the phone as `notStarted` the moment a split is picked, and flips to
+/// `completed` once every exercise is done, at which point we fall back to the gate.
