Rolls up the PRs landed on main after the v0.8.13.30 tag: first-class planning model kind for the plan phase (#951), entry-gate greeting/no-task default method for 岗位流程 templates (#966), external Browser Sandbox provider ppio/novita (#965), config-first browser block backend/sandbox_provider/service_url (#974), system-config-change skill for in-conversation huanxios.json edits (#975), failed-run context carried to next turn via tiered placeholder + on-demand trace (#977), STT short-lived public audio URL (#964), plus portal async-loading feedback (#970), thread-loading scope fix (#972) and image-attachment intent-neutral note (#973). Touches runtime .py, dashboard front-end and skills; no DDL. forward/rollback are an advisory lock plus a source-marker guard, identical bytes, rollback_mode=logical (marker never moves). Rollback is runtime-only: swap the retained previous runtime/manifest and restart. Database, configuration references, credentials and workspaces preserved."
