feat: expose project field in API and CLI

- POST /api/tasks now reads and stores the project field from request body
- GET /api/tasks/{id} returns project in response (via Task struct json tags)
- list command: adds PROJECT column to tabwriter output
- status command: prints Project line when non-empty
- Tests: TestProject_RoundTrip (API), TestListTasks_ShowsProject, TestStatusCmd_ShowsProject (CLI)
