Subject: [PATCH] chore: ignore leftover test temp FILES, not only directories

`tests/.tmp-*/` matched directories only, but the same tests leave plain files
behind when a run dies mid-write. On Windows an exiting child can still hold one
open, so it cannot be deleted either -- an unignorable leftover that blocks the
release preflight's clean-tree check for work unrelated to it. Match both shapes.
