Subject: feat(mail-overview): skeleton for the arrival notifier

A library guard so the test can source the script for its pure
functions without starting a watch loop, and the check itself,
which is one bash script rather than a framework.

+# Watches the notmuch Xapian directory and, on each commit, asks notmuch what

+#   mail-notify.sh --once   process one tick and exit (what the test drives)
