refactor: streamline task path resolution in commands.js (#948)

- Replaced local `tasksPath` variable assignments with direct calls to `taskMaster.getTasksPath()` for consistency and clarity across multiple command functions.
- This change enhances maintainability by ensuring a single source of truth for task paths, reducing redundancy in path handling logic.
