The script missed `getIntl().formatMessage()` calls and `getIntl` imports,
which are used in requestErrorConfig.ts, ErrorBoundary, and OfflineBanner.
Changes:
- Add `getIntl` to I18N_SYMBOLS for import cleanup
- Add `getIntl().formatMessage(` to FORMAT_MESSAGE_PATTERNS
- Handle `const intl = getIntl()` declaration removal
- Add `getIntl` to residual symbol checks
- Add `getIntl` to early-skip detection in processFile
