Agent Skills: handover

Prepare a structured handover document from the current session for a fresh Claude session to continue the work. Use when the user says "/handover", "prepare a handover", "write a handover", "session summary for next time", or when wrapping up a complex debugging/implementation session that will be continued later. Captures problem context, locked decisions, dead ends, running state, key files/commands, artifacts, open questions, and next steps so zero context is lost between sessions.
