Adds a Dreamtune guide under MCP Servers, with sidebar navigation and an index card. It documents hosted Streamable HTTP with the required X-Dreamtune-API-Key header and per-user customUserVars, including saving credentials and manually reinitializing the connection. An alternative stdio configuration pins the published SDK and uses a deployment-managed environment key with an explicit API origin and timeout.

The guide explains selecting tools for chats and Agents, workspace/scoping and billing behavior, idempotency, and troubleshooting. English is updated as the translation source of truth.

Validation on Node 22.23.3 with pinned pnpm 9.15.9:

• pnpm lint, pnpm typecheck and pnpm build passed, including production static generation.
• Both YAML snippets passed the actual MCPServersSchema from LibreChat's data-provider source.
• Ran the production preview locally: the guide and MCP Servers index returned HTTP 200 with the new content/link; the linked customuservars anchor also resolved.
• Full Vitest suite: 434 passed, two failed on Windows in unchanged screenshot-path and locale-preservation tests. Neither implementation is modified by this PR.
• Diff check and staged secret scan passed. No production credential or paid model/tool/compute execution was used.
