✨ feat(sync): multi-language sync wizard, backend locale support, and conflict modal UX improvements
Frontend (web)
- ModelsActions.jsx
- Replace “Sync Official” with “Sync” and open a new two-step SyncWizard.
- Pass selected locale through to preview, sync, and overwrite flows.
- Keep conflict resolution flow; inject locale into overwrite submission.
- New: models/modals/SyncWizardModal.jsx
- Two-step wizard: (1) method selection (config-sync disabled for now), (2) language selection (en/zh/ja).
- Horizontal, centered Radio cards; returns { option, locale } via onConfirm.
- UpstreamConflictModal.jsx
- Add search input (model fuzzy search) and native pagination.
- Column header checkbox now only applies to rows in the current filtered result.
- Fix “Cannot access ‘filteredDataSource’ before initialization”.
- Refactor with useMemo/useCallback; extract helpers to remove duplicated logic:
- getPresentRowsForField, getHeaderState, applyHeaderChange
- Minor code cleanups and stability improvements.
- i18n (en.json)
- Add strings for the sync wizard and related actions (Sync, Sync Wizard, Select method/source/language, etc.).
- Adjust minor translations.
Hooks
- useModelsData.jsx
- Extend previewUpstreamDiff, syncUpstream, applyUpstreamOverwrite to accept options with locale.
- Send locale via query/body accordingly.
Backend (Go)
- controller/model_sync.go
- Accept locale from query/body and resolve i18n upstream URLs.
- Add SYNC_UPSTREAM_BASE for upstream base override (default: https://basellm.github.io/llm-metadata).
- Make HTTP timeouts/retries/limits configurable:
- SYNC_HTTP_TIMEOUT_SECONDS, SYNC_HTTP_RETRY, SYNC_HTTP_MAX_MB
- Add ETag-based caching and support both envelope and pure array JSON formats.
- Concurrently fetch vendors and models; improve error responses with locale and source URLs.
- Include source meta (locale, models_url, vendors_url) in success payloads.
Notes
- No breaking changes expected.
- Lint passes for touched files.
