TwinMind project engine — the hub for goal-driven work with a clear start and end. Use this skill for any project lifecycle operation: create, pause, resume, complete, archive. Also handles project-scoped actions and tasks (adding/completing actions within a project, managing project task lists), progress logging, and linking cards to projects. Triggers: '建立專案', 'create project', '暫停', 'pause', '恢復', 'resume', '完成專案', 'complete', '歸檔', 'archive', '進度', 'log', '列出專案', 'list projects', '專案狀況', or when the user mentions a specific project name in combination with an action/task operation (e.g., '在 build-blog 加個 action'). This is the central skill for anything that references a named project.
