Subject: [PATCH] Replace unmaintained temp dependency with fs.mkdtemp

Use Node's built-in fs.mkdtemp (via fs-extra) with os.tmpdir() to create
temporary directories, removing the unmaintained `temp` npm module and its
`@types/temp` typings. Cleanup semantics from `temp.track()` are preserved by
tracking created directories and removing them on process exit.

Closes #581
