Add composer shortcuts for local Continue and OpenCode terminals and the official DeepSeek Harness Web client, using the current project and model bridge. Manage browser service reuse, stop actions and terminal cleanup. Upgrade DeepSeek Harness to 0.1.7-rc.2 and Cordis to 4.0.4.
Include the coordinated IPC handler extraction and related tests and documentation. Remote native-client coordinator wiring, managed Node consolidation, Ask MCP mappings and full desktop/package acceptance remain unfinished; this commit records the implemented local workflow and supporting SSH groundwork.
Validation: typecheck and lint passed; 267 focused tests passed and 5 skipped. No new real-provider calls were made for this commit. Prior real-model evidence and remaining acceptance work are documented in the feature progress files.
Release note: 本地项目选择 Continue 或 OpenCode 后，可从输入框下方打开原生终端；选择 DS 后，可打开使用当前项目和模型的官方 Web 客户端。客户端使用独立会话，DS 网页关闭后服务继续运行，可在 GoodBuddy 中停止；远程入口尚未完成。
Direct models now use bundled ripgrep for workspace discovery, read files through resumable pages, and edit multiple files with apply_patch. Ask can search and read while Execute retains write access, and fixed total input limits no longer constrain these tools.
Release note: 直连模型现可使用随包 ripgrep 搜索项目、分页读取任意大小的文本，并通过多文件补丁修改代码；设置中的相关能力统一显示为工作区文件和开发工具。
Check cached embedded servers before reuse, isolate concurrent cancellation, and serialize request MCP registration and cleanup. Preserve native controls across session switches and recover usable partial inventories.
Share the bundled offline OpenCode configuration with desktop and Agent launch paths, including model bridge environment forwarding.
Validation: focused tests and typecheck passed; lint passed before the final fixes. The full test run exceeded 120 seconds and reported a DS stdio MCP failure. Current-source Agent host and real suspend/resume validation remain pending.
Release note: 修复切换会话后 OpenCode 原生控件消失及并发取消相互影响的问题，并完善内嵌服务复用检查和桌面、Agent 的离线依赖配置。
