fix: repoint Mumuni refs in Normal-sensitivity contracts to kagentz CT105/.14

Third and final PR of the post-migration contract sweep (ref PRs #54, #55).
Normal-sensitivity contracts per AGENTS.md (any registered agent):

- gpu-fleet: key roster row, Mumuni Agent Profile header + status table
  (thermal-safeguard incident note left as historical record)
- infrastructure-update: apt patch table row; Hermes config path block
  corrected to /home/hermes/.hermes + system unit /etc/systemd/system/
  hermes-gateway.service (was /root/.hermes + user unit)
- infrastructure-maintenance: Hermes gateway health-check target
- inference-optimization: apply-agent-compression host + config_path

All values verified live on kagentz 2026-08-29 (hostname, IP, user,
systemd unit, /home/hermes/.hermes). Abiba-owned refs (.24 pi agent,
GPU monitor :9100) and CRITICAL files intentionally untouched - flagged
to Abiba via relay #739.

Refs PR #54, #55; relay #738/#739.
