Summary

Part of #36898.

Migrate the app-detail-collapse-or-expand preference away from direct localStorage access in the app detail sidebar flow.

Reproduction

web/AGENTS.md disallows direct localStorage, window.localStorage, or globalThis.localStorage access in app code. On main, this storage key still had direct app-code access in:

• web/app/(commonLayout)/app/(appDetailLayout)/[appId]/layout-main.tsx
• web/app/components/app-sidebar/index.tsx

Root cause

The app detail layout and sidebar still read/wrote the raw sidebar mode preference directly, while the dataset detail layout already uses the @/hooks/use-local-storage boundary for the same key.

Changes

• Use useLocalStorage<string>('app-detail-collapse-or-expand', 'expand', { raw: true }) when initializing the app detail sidebar mode.
• Use useSetLocalStorage<string>('app-detail-collapse-or-expand', { raw: true }) when persisting sidebar mode changes.
• Update the existing sidebar persistence test to assert the storage hook setter path.
• Prune the related no-restricted-globals suppression counts.

Tests

• Passed: git diff --check
• Passed: node -e "JSON.parse(require('fs').readFileSync('eslint-suppressions.json', 'utf8'))"
• Passed: git grep -n -E "localStorage\\.(getItem|setItem|removeItem)\\('app-detail-collapse-or-expand'|window\\.localStorage.*app-detail-collapse-or-expand|globalThis\\.localStorage.*app-detail-collapse-or-expand" -- web/app web/context web/service || true returned no matches
• Attempted: pnpm -C web test app/components/app-sidebar/__tests__/index.spec.tsx
  • Blocked locally by Corepack signature verification with the default Node 22.2.0 shim.
• Attempted workaround: PATH="$HOME/.nvm/versions/node/v22.13.0/bin:$PATH" npx -y pnpm@11.5.0 -C /Users/liumin/Documents/OpenSourceContributions/dify/web test app/components/app-sidebar/__tests__/index.spec.tsx
  • Blocked before test execution by the workspace dependency policy using local registry metadata: @vitejs/plugin-rsc@0.5.27 Missing time for version 0.5.27 of @vitejs/plugin-rsc in metadata.

Screenshots/Logs

Not applicable; behavior and UI are unchanged.
