+- `feat(gate): disable web app — Telegram Mini App only mode` — added `src/middleware.ts`; when `WEBAPP_ENABLED` env var is not `'true'`, all routes except `/telegram`, `/api`, `/_next`, and static assets redirect to `/telegram`. Set `WEBAPP_ENABLED=true` in Arcane project env to re-enable the full web app with no rebuild.
