m17hr1l ee387abcd4 stage-21: swap inference server to psyc-v5 adapter ...

v5 trained on 598 ex/task (20× v4's 30), with --defang-frac 0.5 over
the new ThreatFox + MalwareBazaar + OTX corpus. Final train_loss 0.3225
vs v4's 0.7397 (56% reduction), 60m20s wall clock on a 3090.

Live eval before swap:
- severity (botnet, ONLINE): v4 high / v5 high — tied, both correct
- ioc_extraction with defanged input (hxxps://, [.], (.), [dot]):
    v4 kept hxxps:// in output (failed canonicalization)
    v5 returned canonical https:// — defang training paid off
- ioc_extraction on real OTX-style prose (never trained on this shape):
    v5 cleanly extracted 2 domains + 1 IP + 1 SHA256 + 1 CVE

Cockpit /api/inference-status confirms the swap:
  {"online":true,"adapter":"/data/adapters/psyc-v5/final"}
