Subject: [PATCH] arti: add patch for TROVE-2026-024

TROVE: https://gitlab.torproject.org/tpo/core/team/-/wikis/NetworkTeam/TROVE

an invalid assumption of ASCII in port policies could allow a malicious
directory cache to crash arti clients. this issue was originally
publicly reported at
https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/4049
and the final fix was merged as
https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/4062. this
allows for DoSing clients, and has been allocated the the TROVE-2026-024
id with medium severity. we fetch the patch for it here, and may upgrade
to 2.4.1 or similar if upstream releases one.
