Subject: [PATCH] fix: handle empty menu_options in mo purge to prevent unbound
 variable error (#547)

When no artifacts are found during scanning, `menu_options` remains an
empty array. With `set -euo pipefail` active, expanding `${menu_options[@]}`
on an empty array causes a fatal "unbound variable" error (line 1325).

Add an early-return guard after the spinner stops: if no items were found,
print a friendly "No artifacts found to purge" message and exit cleanly.

Fixes #546
