Replaces stale phase25_* checkpoint paths with the current janus_<ds>_seed<S>
layout under route_comparison/, adds CICIoT2023 to PCAP_GLOBS / WITHIN_DIRS,
and removes the per-dataset n_atk caps so within-dataset eval uses the same
sample budget as JANUS phase1.
Adds cython (3.2.4) — required by Kitsune's KitNET cluster compile path.
