docs(host-agent): drop stale --no-deps from post-install recreate explainers

PR Light-Heart-Labs#1021 dropped --no-deps from the install command path. Three comments
in this branch's neighborhood still referenced the old form when
explaining WHY the post-install core recreate is needed:

  bin/dream-host-agent.py:348   docstring of _post_install_core_recreate
  bin/dream-host-agent.py:1260  call-site comment in _handle_install
  tests/test_host_agent.py:328  comment block above TestPostInstallCoreRecreate

The underlying causal claim is unchanged: docker compose up -d <ext>
won't recreate already-running siblings without --force-recreate. Comments
now describe the present-day install command accurately, with the missing
--force-recreate flag named as the reason recreate is required, instead
of the no-longer-passed --no-deps flag.

No behaviour change. 45 host-agent tests still pass.
