integration: repo-qualified goal_branches rows, plan-12 doc rot swept

parse_push_state labels array rows 'repo: branch' when the daemon's
full {repo, branch, pushed} shape arrives (multi-repo goals stay
distinguishable); bare-branch and map forms render unchanged. Swept
the subtask-era remnants: dead parent_task_id view fields, stale
next-task/tasks-list/callback doc comments, the timeline park wording,
the task-create form doc.
