feat(server): improve task CLI with steering, execution order, and planner guidance

- Fix steering notes to check scope task instead of leaf task
- Fix NOT_DONE replan to use scope for bird's eye view
- Pass reason to planner prompt ("Why you were called" section)
- Add execution-order.ts with reusable computeExecutionOrder and buildSortedChildrenMap
- Make 'tree' an alias for 'plan' command
- Add comprehensive help text for run command and acceptance criteria
- Add planner guidance for propagating requirements to subtasks
