Summary

• Bump `expo` to `~55.0.18` and align all SDK-managed peers via `expo install --fix` — `react` → 19.2.0, `react-native` → 0.83.6, `expo-*` → 55.x line, `eslint-config-expo` → 55.0.0, plus `react-native-gesture-handler` / `-reanimated` / `-screens` / `@types/react` peers that RN 0.83 requires.
• Register `expo-sharing` as a config plugin in `packages/app/app.json` — required by the SDK 55 plugin contract; `expo install --fix` added it automatically.
• Slide `renovate.json` `allowedVersions` ceilings to the SDK 55 line so Renovate keeps offering within-SDK patches but stops surfacing SDK-coupled majors. Add `eslint-config-expo` to the same pin group as `expo` / `@expo` so it can't drift independently again (this is what created PRs Update dependency eslint to v10 #35 and Update dependency eslint-config-expo to v55 - autoclosed #36 in the first place).
• Update the `Expo SDK 54` reference in `CLAUDE.md`.

This unblocks the ESLint v10 update path indirectly: ESLint 10 still needs `eslint-plugin-react` to ship its v10 fix (jsx-eslint/eslint-plugin-react#3979), but at least `eslint-config-expo` is now on the SDK-current major.

Background

Renovate offered `eslint-config-expo@55` (#36) and `eslint@10` (#35) standalone, but neither could merge — `eslint-config-expo@55` failed the `expo install --check` gate (SDK 54 expects `~10.0.0`), and `eslint@10` blew up at lint time because `eslint-plugin-react@7.37.5` still calls `context.getFilename()` (removed in ESLint 10). The clean way out is to bump the Expo SDK itself, which this PR does.

Test plan

CI-equivalent checks all green locally:

• `pnpm --filter @seam/app exec expo install --check` (EXPO_OFFLINE=1)
• `pnpm format:check`
• `pnpm -r lint`
• `pnpm -r typecheck`
• `pnpm -r test` — 198 tests passed across `shared` / `domain` / `app`
• `pnpm --filter @seam/app exec expo export --platform ios` — Metro bundle 5.7 MB

Pending verification (local-only — CI can't run iOS simulator)

• `cd packages/app && pnpm prebuild` — regenerate `ios/` against SDK 55 / RN 0.83
• `pnpm ios` — boot in simulator, exercise tabs (Home / Closet / Wishlist / Compare / Stats / Settings), item & candidate CRUD, photo pick, notification reminder, JSON / CSV export+import, data reset
• `maestro test .maestro/` — full E2E flow

Follow-ups

• After this lands and PR Update dependency eslint to v10 #35 / Update dependency eslint-config-expo to v55 - autoclosed #36 close, wait on Fix ESLint v10 RuleContext API removal (follow-up to #3972) jsx-eslint/eslint-plugin-react#3979 for ESLint v10 support; Renovate will re-offer ESLint 10 once the new `eslint-plugin-react` ships.
