An embedded ConPTY session leaves its worktree changed but never touches
task status, so hand-driven work had no path into the review/merge flow.
Add SubmitTaskForReview: commit the worktree (same auto-commit as a headless
run), then transition Idle/Failed -> WaitingForReview via the new
TaskStateService.SubmitInteractiveForReviewAsync. Approve then merges it.
Surfaces: a 'Submit for review' button in the detail work console (shown for
an Idle/Failed task with a worktree) and on the ConPTY Command Center pane
header (task-based panes; closes the pane on success). Tests cover the new
transition (Idle/Failed accepted, Running/Queued/Done/Review rejected).
DeleteTask never re-evaluated a WaitingForChildren parent, so deleting
the last non-terminal child left it stuck (the BlockedByTaskId SET NULL
FK only repairs the blocked chain, not parent status). Expose
TaskStateService.TryAdvanceParentAsync on the interface and call it
from ExternalMcpService.DeleteTask after a child delete.
Move interface declarations into per-area Interfaces/ subfolders, merge the
small task-list filter classes into StatusFilter/SmartFlagFilter, and simplify
related services, converters and hub DTO handling.
