feat(tasks): support parent-owned child tasks
```
Execution notes:
- Added `ChildTaskCompletionService` and `ChildTaskCompletionResult`.
- Completing a child now completes its parent only when all direct children are complete.
- Completing one child does not complete siblings.
- Partial child completion leaves the parent incomplete and exposes `canCompleteParentExplicitly`.
- Explicit parent completion force-completes remaining direct children and records `forceCompletedChildIds`.
- Parent completion is direct-child only; no generalized dependency graph behavior was added.
- Completion propagation updates task status and `updatedAt` without adding duplicate statistics events.
- Added tests for all-child auto-completion, parent force-completion, partial completion, sibling safety, and explicit parent-complete result metadata.
- `dart format lib test`, `dart analyze`, `dart test`, and `git diff --check` passed.

are pushed by the normal scheduler, required visible overlaps are reported, and
locked overlaps are tracked as hidden data rather than rendered as normal tasks.
Child tasks are direct parent-owned tasks, not dependency graph nodes. Completing
all direct children can complete the parent, and explicitly completing a parent
can force-complete its direct children. Scheduling still treats child ownership
as metadata and does not block placement based on parent/child state.
## Persistence direction
MongoDB is the committed persistence target. The V1 scheduling core should still
