lpm: Skill for Claude Code

Makes the lpm Link App Store screenshots again whenever the app changes, with no clicking in the app: scripts/shots.js builds a screenshot copy of the app, launches it once per screen in the iOS Simulator, and composes the store images. The one manual step is opening the iPhone Duo (below).

node scripts/shots.js all          # build, prepare, capture, compose (~2.5 min)
node scripts/shots.js capture --only diff,stats --device iphone
node scripts/shots.js compose      # after editing captions only (seconds)
node scripts/shots.js cleanup      # clear status bars, shut down simulators it booted

• build copies mobile/ to ~/Library/Caches/lpm-app-store-shots/src (the repo is never touched), applies the PATCHES in scripts/build.js, adds scripts/swift/*.swift, runs xcodegen and a Release simulator build. The copy shows Demo Mode as a real Mac: no purple Demo banner, the Mac is "MacBook Pro", the status line reads "Connected · on your network", a busier sample seed (ShotSeed.swift), and the storefront Claude session already finished and waiting on you.
• prepare finds (or creates) the simulators named in shots.json, sets US English (the clock reads 9:41, not 09:41; reboots once), a full non-charging battery, light mode, installs the build and launches it once (the first launch after an install is slow).
• capture launches the app with LPM_SHOT_ROUTE=<route> (ShotDriver.swift enters Demo Mode and pushes the route), waits, and saves simctl io screenshot at native size (the device's display when it has one).
• compose (compose.swift) writes the store images without an alpha channel (App Store Connect rejects one) and a contact sheet per device.

Output: ~/Pictures/lpm-link-app-store/<version>/ with iphone-6.3/NN-name.png, ipad-13/NN-name.png, iphone-duo-outer/NN-name.png, iphone-duo-inner/NN-name.png, sheet-<device>.png and source/raw/. The version comes from mobile/ios/project.yml; --version <v> writes elsewhere (use it to try changes without replacing a set the user already has).

shots.json: devices (simulator name, folder, store size, screenRadius of the display in raw pixels, one number or top-left/top-right/bottom-right/bottom-left, cutout for the camera simctl leaves out as x/y/width/height in raw pixels, and for the Duo the pose and the display to capture) and shots in store order, each with name, route, title (\n for the line break, two lines at most), subtitle (one line, about 50 characters on iPhone), devices, an optional wait in seconds (default 4), and optional captions to give one device its own title/subtitle. Route steps, joined by >, are pushed in order: list · project:<name> · terminal:<project>/<terminalId> · changes:<project> · usage · stats · activity · automations · automation:<project>/<jobId>. Demo names: projects storefront, api-gateway, analytics, mobile-app, blog, …; terminal demo-storefront-claude; automation nightly-tests (mobile/ios/Sources/LpmMobile/DemoWorld.swift, DemoJobs).

iPhone Duo Apple lists two Duo sizes, closed (outer display, 1398x2034, display: primary) and open (inner display, 2007x2853, primary-1), without saying yet whether a listing needs both, so the skill makes both from one simulator: duo-closed has the iPhone set, duo-open the iPad set. The display of the other pose is dark. The Duo boots closed, every boot, so duo-closed captures on its own; nothing in simctl folds it, so duo-open waits (up to 5 minutes) printing "set it to Open, in portrait, in Device Hub" until the inner display shows a portrait picture. Run all in the background, and when that line appears open it with computer use: Device Hub (com.apple.dt.Devices) → iPhone Duo → bottom bar, the rightmost pose button ("Open"; the first click may only focus the window), then the rotate button left of the poses once, to portrait. Closed is the leftmost pose button. Then move the pointer off the device: hovering over it acts as a pointer in iOS, and the terminal shows a scroll bar in the shots. The outer display's hinge-side corners are nearly square and its camera is a circle top-right, which compose draws back in.
