revert: drop co-gated prose edits (gpu-fleet, infrastructure-control) — script-only scope per captain decision

The no-mistakes document step had auto-updated the .8 systemd unit name
(llama-server -> llama-chat-api.service) in gpu-fleet.prose.md and
infrastructure-control.prose.md. Those contracts are co-gated with another
agent and cannot be amended inside a script-scope task (firstmate decision
2026-09-08, key prose-doc-step-scope); the unit-name doc sync is separate
follow-up work. This restores both files to their origin/master content.
The litellm-self-heal.prose.md agent-health-check v3/env.sh description
update (same document commit) is intentional and kept.
