Log Message:
arti: update to 1.3.2.

# Arti 1.3.2 — 7 January 2025

Arti 1.3.2 continues development on RPC,
and includes preparatory work for relay support and
service-side onion service denial-of-service resistance.

# Arti 1.3.1 - 2 December 2024

Arti 1.3.1 continues development on onion services,
the RPC subsystem, and relay infrastructure.

Additionally, this release fixes a major bug in Arti's channel management code,
where in some circumstances, canceled pending channel entries
were not being cleaned up properly, preventing Arti from building new channels
to their target relays.
