Expo SDK 58 - #53

expo install --fix moved every Expo package to 58 together, with
React Native 0.88.1, React 19.3, react-native-webview 14.0.1 and the
slider 5.2.1, and added expo-status-bar's config plugin. Dependabot's
bump (#49) moved expo alone and left the nine modules on 57.

What SDK 58 changed here:

- withSceneLifecycle.js is gone. SDK 58's prebuild writes the
  AppDelegate this plugin produced — window and React Native's start
  left to the scene delegate — and generates SceneDelegate.swift with
  the scene manifest naming it. A prebuild without the plugin gave an
  identical AppDelegate.swift; the plugin's only difference was a
  manifest naming the base EXExpoAppSceneDelegate. CLAUDE.md says so.
- React Native 0.88 types refs by instance: ViewInstance for the drop
  zone, TextInputInstance for the OTP boxes and the password field,
  and a list footer is undefined rather than null.
- File.write() is async now; the Storage screen uses writeSync, so
  the count it shows is the one written.
- @expo/cli no longer depends on zod, so its override is dropped;
  glob and minimatch stay (@expo/cli still asks glob ^13).
- Release builds are minified by R8 by default.

Checked: tsc --noEmit; expo install --check; a clean prebuild for
both platforms. On devices, with Mobium's checks at main 6213f11:

- Android 15 emulator, the minified release: 20 of the 21 checks
  CLAUDE.md names pass first time — crashes, graybox, graybox-edges,
  graybox-hooks, audio and biometric among them, the modules R8 could
  have stripped. mobium-app.sh failed once, its first run after the
  install, on an empty ref for Back after the WebView screen, then
  passed four runs in four. Not compared against SDK 57.
- iOS 27.0 simulator (iPhone 18 Pro), Release: launches under SDK
  58's own SceneDelegate, the one iOS 27 requires; mobium-app, login,
  keyboard, web-type, gestures, clear-data, crashes, source, frames
  and otp pass. dialogs.sh fails at the paste prompt, and fails the
  same way on SDK 57's build from main, fresh installs both: on this
  simulator the seeded clipboard raises no prompt. Not this change.
