"""Gateway identity-file readers expand a literal ``~`` in HERMES_HOME.

``python -m gateway.run`` never passes through the CLI's ``normalize_hermes_home_env()``, so the
process-level home readers (PID/lock/status, lifecycle ledger, heartbeat) must expand on their own
or a fish-style ``HERMES_HOME='~/.hermes'`` lands the identity files under ``<cwd>/~/.hermes``.
