- Plugin SDK/models: add a shared manifest-backed provider catalog builder and move Qianfan, Xiaomi, NVIDIA, Cerebras, Mistral, Moonshot, DeepSeek, Tencent TokenHub, and StepFun provider catalogs onto their plugin manifest `modelCatalog` rows. Thanks @shakkernerd.

- Plugin SDK/models: move BytePlus and Volcano Engine standard and plan-provider catalogs into plugin manifest `modelCatalog` rows and remove the now-unused Volcengine-family shared catalog SDK subpath. Thanks @shakkernerd.

- CLI/models: move Fireworks and Together AI fixed provider catalogs into plugin manifest `modelCatalog` rows so provider-filtered listing can use manifest-backed static rows. Thanks @shakkernerd.

- CLI/models: move Groq's fixed text model catalog into the Groq plugin manifest and declare its setup auth env metadata so provider-filtered listing can use manifest-backed rows without deprecated auth metadata. Thanks @shakkernerd.

- Channels/Yuanbao: register the Tencent Yuanbao external channel plugin (`openclaw-plugin-yuanbao`) in the official channel catalog, contract suites, and community plugin docs, with a new `docs/channels/yuanbao.md` quick-start guide for WebSocket bot DMs and group chats. (#72756) Thanks @loongfay.

- Channels/QQBot: add full group chat support (history tracking, @-mention gating, activation modes, per-group config, FIFO message queue with deliver debounce), C2C `stream_messages` streaming with a `StreamingController` lifecycle manager, unified `sendMedia` with chunked upload for large files, and refactor the engine into pipeline stages, focused outbound submodules, builtin slash-command modules, and explicit DI ports via `createEngineAdapters()`. (#70624) Thanks @cxyhhhhh.

- Plugins/startup: migrate bundled plugin manifests to explicit `activation.onStartup` declarations so Gateway startup imports only the bundled plugins that intentionally register startup-time runtime surfaces. Thanks @shakkernerd.
