- introduce a new feature-oriented TaskMaster domain under src/components/task-master
- add typed TaskMaster context/provider with explicit project, task, MCP, and loading state handling
- split task UI into focused components (panel, board, toolbar, content, card, detail modal, setup/help modals, banner)
- move task board filtering/sorting/kanban derivation into dedicated hooks and utilities
- relocate CreateTaskModal into the feature module and keep task views modular/readable
- remove legacy monolithic TaskList/TaskDetail/TaskCard files and route main task panel to the new feature panel
- replace contexts/TaskMasterContext.jsx with a typed contexts/TaskMasterContext.ts re-export to the feature context
- update MainContent project sync logic to compare by project name to avoid state churn
- validation: npm run typecheck, npm run build
