The scrubbed builder rewrites HOME to the profile home in containers and
profile home mode (the official image does this by default). These are
third-party programs whose own config and logins live under the user's
HOME: ~/.openviking, the raft CLI profile, ~/.config/buzz. The openviking
change copied the parent's HOME back, which is itself a profile home
when Hermes runs under one; use HERMES_REAL_HOME, which the builder
already computes, for all three.
