Overnight agent guardrails

Use this when a user wants to leave a coding agent running unattended and needs the run to be bounded, resumable and checkable afterwards.

When this applies

• "leave it running overnight", "run this unattended", "let it work while I sleep"
• a run that kept going and produced hours of output nobody verified
• wanting a hard ceiling on what one unattended run can cost
