fix active_pr continue respawn

[junie-the-developer]

What

Allow ready-lane same-task continuation to recover incomplete active_pr runs without creating a new task or duplicate pull request, while retaining the duplicate-work protection for successfully completed runs with a live PR.

Changes

• Step 1 — Updated the respawn guard to allow continuation after incomplete recovery outcomes such as crashes, reclaim, orphan recovery, and timeouts.
• Step 1 — Preserved blocking after completed work, with the existing deliberate-clear, never-run, and closed/merged-PR exceptions.
• Step 1 — Added regression coverage for blocking, clear signals, recovery continuation, and re-arming after a later completed run.
• Step 1 — Updated Kanban help and documentation to explain automatic continuation for incomplete recovery and the explicit unguard override after successful PR work.
