Secrets::Editor
secrets edit helper: write plaintext to a mode-0600 tempfile,
spawn $EDITOR (default vi) on it, return the edited buffer.
The tempfile is wiped (best-effort) and deleted in ensure,
whether the editor succeeded or not.
Why not stream through the editor? Most editors don't accept
stdin/stdout for buffer editing — they need a file path. The
tempfile is on /tmp (or $TMPDIR) for the duration of the edit,
mode 0600 so other users on the box can't peek.
