Add App Store screenshot harness + listing metadata

DEBUG-only screenshot support (seeded sample data via ScreenshotSeed, per-screen
launch args, screenshot roots for both apps) so iPhone + Apple Watch App Store
shots can be captured deterministically from the simulator — all excluded from
release builds. Also seed ExerciseView's set-grid progress in init so it renders
correctly on the first frame. Adds Scripts/metadata/ as the listing source of
truth (copy, URLs, review notes, and the captured screenshots).

+Workouts Plus is a workout tracker for iPhone and Apple Watch. Plan your routine on the phone, then leave it in your pocket and run the whole session from your wrist.
+
+PLAN YOUR SPLITS
+- Organize exercises into reusable routines with their own colors and icons
+- Start from a built-in catalog of bodyweight and machine exercises, or add your own
+- Set default sets, reps and weight — or a timed duration — for each exercise
+
+RUN IT FROM YOUR WRIST
+- Start a workout on iPhone and your Apple Watch opens straight into it
+- Each exercise runs as a HIIT-style cycle: a count-up work phase, then a rest that counts down with a haptic countdown before the next set slides in
+- Tap One More for a bonus set, or Done to finish and move on
+- Set your rest length once on iPhone and it syncs to the watch
+
+PROGRESS THAT KEEPS UP
+- Finish a set on the watch and the iPhone advances in real time — no need to touch your phone
+- Per-exercise weight-progression charts show how you're trending across past sessions
+
+YOUR DATA, IN YOUR ICLOUD
+- Everything is stored as plain files in your own iCloud Drive — browsable in the Files app and synced across your devices through Apple, never through a server of mine
+- No accounts, no ads, no tracking
+- iCloud is required
+
+Built for lifters who plan on the phone and train from the wrist.

To try it: open the iPhone app, tap \"Add Starter Splits\" in Settings (or create a split), then start a workout from a split. Starting a workout launches the paired Apple Watch app into the session via HealthKit (allow the Health prompt), so please review on a paired Apple Watch. On the watch, tap an exercise and swipe through the work/rest pages; completing a set syncs back to the iPhone in real time. The HealthKit permission is used only to launch and run the on-watch workout session — the app does not read your health data."
