Replace hardcoded Chinese string in useStorageInfo with i18n key

[kanweiwei]

web/src/hooks/useStorageInfo.ts line 153 has a hardcoded Chinese string:

cacheSizeFormatted: workspace.cacheSize ? formatBytes(workspace.cacheSize) : '计算中...'

The string '计算中...' should use an i18n translation key instead.

What to do:

1. Read web/src/hooks/useStorageInfo.ts around line 153
2. Find or add an appropriate i18n key (e.g. storage.calculating or reuse common.loading)
3. The hook doesn't use useT() — you may need to import from the i18n package directly, or restructure slightly
4. Add the key to all locale files in packages/i18n/src/locales/ (en-US, zh-CN, ja-JP, ko-KR)

Skills needed: TypeScript, basic i18n concepts

Estimated time: 15 minutes

The hardcoded "计算中..." string in useStorageInfo.ts should indeed use i18n. I'd handle this by adding a storage.calculating key to all locale files and importing the translation function directly since hooks can't use useT(). Can have a PR up in under an hour—I regularly implement i18n solutions in TypeScript/Next.js projects.
