Summary

Adds full Russian (ru) support for the DB-GPT web UI, migrates hardcoded Chinese UI strings to i18n, and includes dev/runtime fixes for standalone next dev on Windows/npm.

Locale & infrastructure

Add web/locales/ru (common, chat, flow) with key parity to en/zh.
Register ru in web/app/i18n.ts (supportedLngs, fallbackLng: 'en').
Language switcher cycles en → zh → ru → en; Ant Design ru_RU locale.
scripts/check_web_i18n.py — CI-friendly key parity check.
Maintenance scripts: fill_ru_from_en_dict.py, apply_ru_manual_batch.py, apply_ru_common_remaining.py, sync_ru_locale_quality.py.

UI i18n migration (phase 2)

Replace hardcoded Chinese UI strings with t() / i18n.t() across main pages and components (playground, chat panels, share, construct flows, charts).
Rename legacy ui_* hash keys to semantic keys; neutral demo example cards (no vendor-specific branding).

RU quality & completeness (latest commit)

Complete ru/common and ru/chat translations (user-facing strings; keep universal terms like URL, PDF, DBGPTS, filenames).
Fix module-level i18n.t() usage (SSR-safe), flow parameter labels, knowledge recall modal strings.
npm overrides for d3-* v2 (fixes Cannot require() ES Module d3-shape with npm install).
web/.env.template documents API_BASE_URL for standalone frontend dev.
Softer API error handling: no toast spam on network errors when backend is down; apiInterceptors messages use i18n keys.

Out of scope (follow-up)

Backend Python i18n (DBGPT_LANG)
Hardcoded English message.success/error toasts (~15 call sites)
Documentation site (docs/)
Mobile UI smoke-test

Test plan

python scripts/check_web_i18n.py — all locales pass
cd web && cp .env.template .env.local — set API_BASE_URL=http://localhost:5670
Start API: uv run dbgpt start webserver --config configs/dbgpt-proxy-openai.toml (or your provider)
cd web && npx next dev — open http://localhost:3000
Toggle language en/zh/ru on sidebar; verify main playground, chat, knowledge, flow variable modal
Confirm skills/knowledge lists load when API is up (empty, no crash when API is down)

Ru locale will be implemented in several phases.

Replace inline Chinese labels and messages with t()/i18n.t() across chat, construct, evaluation, and mobile pages. Add ~150 locale keys to en/zh/ru and helper scripts to validate parity and module-level translations. Co-authored-by: Cursor <cursoragent@cursor.com>

…I strings - Sync ru translations from en/deploy dictionaries (no CJK left in ru/) - Rename 147 ui_* keys to semantic names (deleted_successfully, etc.) - Neutralize demo cards (annual report filename, generic fin-report copy) - i18n for share replay, sidebar relative time, pagination, collapse/expand - Add maintenance scripts for RU sync and key rename apply Co-authored-by: Cursor <cursoragent@cursor.com>

Finish ru locale coverage for common/chat/flow, fix module-level i18n calls and chart labels, add npm overrides for d3 on Windows, soften API error toasts when the backend is offline, and add locale sync scripts. Co-authored-by: Cursor <cursoragent@cursor.com>

Replace hardcoded Chinese SSE titles (思考中) with language-aware _agent_thinking_title() / _agent_react_detail() using CFG.LANGUAGE or DBGPT_LANG. Add clearer html_interpreter errors when file_path is missing. Map legacy SSE strings in ManusLeftPanel via i18n keys. Co-authored-by: Cursor <cursoragent@cursor.com>

- Default UI language to ru on this branch; persist language in storage - chat-context and index SSR/router fixes for Pages Router - server-deploy/: Docker Compose, entrypoint patches, web build scripts for a localized private instance (optional; superseded by agent i18n in app) Co-authored-by: Cursor <cursoragent@cursor.com>
