Detailed Description

RAII guard around a freshly mkdtemp'd /tmp directory.

Wraps the boilerplate every external-tool launch shares: create a private 0700 directory, write the Tseytin CNF and any sibling files into it, and on scope exit unlink each tracked file and rmdir the directory. If the body throws (missing tool, runtime failure, malformed output), the destructor still runs and the /tmp leak is avoided. Pass keep() in the verbose-debug arm to leave the artifacts on disk for inspection.

Best-effort: the destructor swallows unlink/rmdir errors because it must not throw during stack unwinding.
