Bot-to-bot message_agent delivery builds both transport argvs (local
teammate chat and peer dm) with a bare "hermes" as argv[0]. Since #96631
the delivery runner spawns under terminal_tool's isolated host-local
environment, which does not inherit the gateway's PATH — so on
docker/service installs (venv at /opt/hermes/.venv) every delivery exits
with FileNotFoundError: 'hermes'.
Resolve the CLI with bot_relay._hermes_cli() (#93590) — the venv sibling
of this interpreter, then shutil.which, then the bare name — at both
argv construction sites. The turn-lock matcher in _delivery_lock()
already matches argv[0] by basename, so absolute paths lock exactly as
before.
