feat(mcp): update_task kann isManual setzen + List-Handler stellt seinen Task auf Review

Teil A: update_task bekommt einen optionalen isManual-Parameter (null =
unveraendert); TaskDto/TaskRefDto spiegeln IsManual zurueck.

Teil B: neuer submit_task_for_review MCP-Tool (LifecycleMcpTools) laesst
einen Handler-Task selbst auf WaitingForReview gehen -- fuer einen
worktree-losen Task wird HandlerHeadCommit vom aktuellen HEAD gestempelt,
sonst werden offene Aenderungen committet. Die Submit-Logik ist aus
WorkerHub.SubmitTaskForReview in InteractiveReviewSubmissionService
extrahiert; der Hub ruft sie jetzt nur noch auf. Der Merge-Prompt-Default
weist die Endzweige (merge ohne Rerun, merge_final) an, den eigenen
Handler-Task nach der Summary einzureichen.
