feat(wave1): populate @mosaic/types and migrate @mosaic/queue imports

- @mosaic/types: full type definitions extracted from queue, bootstrap, context packages
- @mosaic/queue: type imports now sourced from @mosaic/types via workspace:*
- Task, TaskStatus, TaskPriority, TaskLane, CreateTaskInput, etc. centralised
- Runtime constants (TASK_STATUSES etc.) remain in queue/src/task.ts

packages/queue/tests/cli.test.ts
