"""`hermes profile delete|rename` never removes another install's gateway service.

Service names derive from the profile name and the user unit dir is account-anchored, so a scratch-HOME
delete of `coder` named the ACCOUNT's real `hermes-gateway-coder` unit and disabled, stopped and unlinked
it. Every service-manager seam is a recorder; nothing here executes one.
