fix(alignment): resolve /root/ hardcoding and stale tanko-DSH references

F1: agent-health-check.py now resolves the home directory from the agent's
user field via a shared helper (get_user_home) instead of hardcoding /root/.
This fixes the false-positive wrapper-missing:tanko report — tanko has a
working wrapper at /home/jerome/.local/bin/hermes, but the check was looking
in /root/.local/bin/.

F2: Updated stale references that described tanko as DSH-only:
- hermes-zulip-restore.prose.md: tanko excluded — hybrid (DSH + Hermes)
- hermes-zulip-plugin.prose.md: tanko excluded — hybrid (DSH + Hermes)
- infrastructure-control.prose.md: tanko is hybrid (DSH + Hermes) agent
- docs/probe-drift-round2-evidence.md: marked as historical record with
  dated note explaining that the DSH-only observations reflected the
  /root/ hardcoding bug, not the underlying truth
