Brooklyn Nicholson 9d9a50c2bc test(cli): pin the hermes serve decoupling contract
Add a focused contract test for the headless `serve` command (routes to the
shared dashboard handler, headless by default while `dashboard` is not, accepts
the legacy --no-open, shares the same runtime/lifecycle flag surface). Also
refresh the dashboard.py module docstring to cover both commands.

"""Contract for the headless ``hermes serve`` backend command.
``serve`` is what the desktop app and remote backends launch — the same gateway
as ``dashboard`` (shared handler) but always headless, and decoupled in name so
the desktop never invokes ``dashboard``. These tests pin that contract:
- ``serve`` routes to the same handler as ``dashboard``;
- ``serve`` is headless by default, ``dashboard`` is not;
- both expose the identical server-runtime flag surface.
