session-handoff

1. Call the Skill tool with "handoff-auto", passing the argument. Keep the path it prints.
2. Append ## Board status to that document: issues touched; complete / partial / blocked; deviations from the issue; new ideas not in the issue.
3. Move each issue's card (BOARD.md; its Target repo section first: on a fork, ask before writing): already closed by a merged PR → leave it, note it under ## Board status; complete → In Review; partial or blocked → stays In Progress, plus an issue comment saying why if blocked. Complete = the issue's done-when is met; list any deviations under ## Board status but don't change the done-when. Projects board with no In Review option → leave the card In Progress, note it in the handoff, and point at IN-REVIEW-OPTION.md. Under a guarded agent (implementer/manager: read-only gh), gh writes (card moves, comments) belong to the caller: skip them and list them under ## Board status as manual steps.
4. Print the handoff path as the last line.

A repo's CLAUDE.md/AGENTS.md may prescribe filename or required sections; follow it. Commit the handoff or not per the handoff-auto skill's TRACKING.md.
