Cleanup

Undo this session's footprint so the machine is as it was before the task, plus the delivered work.

The one rule

Touch only what this session can prove it created. Proof is evidence from this session: a command you ran, a path you wrote, a PR you opened, a process you started. Machines are shared. Other sessions and threads work in the same checkouts, /tmp, and caches, so "it looks stale" or "it is big" is not proof. Anything you did not create goes in the report, not the trash.

When ownership is unclear, keep the item and report it.
