test: teach the run-command config stubs about optimizer_harbor_args

Two tests in test_v05_harbor_http.py build the build-config as a
SimpleNamespace carrying only the attributes run_command reads, so adding a
field to HarborBuildConfig breaks them with an AttributeError that surfaces
only as a non-zero exit code. Same convention as when agent_env was added:
the stub grows with the config.

The mirror of that also applied to this branch's own test, whose _Config
predates agent_env and so broke once both fields were in the same code path.

Suite now matches the base branch exactly: 11 pre-existing failures, none
new.
