feat: expand multi-runtime workflows for 0.10.0

GoodBuddy previously exposed Runtime capabilities, MCP assignments, plugin controls, context compaction, usage reporting, and task-completion behavior through incomplete or inconsistent paths. This release unifies managed OpenCode, Continue, and DeepSeek Harness controls; adds DSH plugin and image workflows; strengthens MCP and Runtime lifecycle bounds; fixes Windows notification activation; validates cross-architecture packages; and presents the approved bilingual four-section release notes.

The DSH plugin marketplace remains a default-off preview whose trusted third-party code runs with current-user permissions. Ask remains read-only, Execute keeps approval controls, and context compaction may use the selected model without deleting GoodBuddy chat history.

Release note: GoodBuddy 0.10.0 重点完善多 Runtime 工作流，统一 OpenCode、Continue 与 DeepSeek Harness 的能力、MCP、插件和上下文管理，并提升长对话、多会话与任务通知的连贯性。
