"""ORCH-41: tests for resolve_agent_effort + effort validation + flag assembly.

Mirrors test_resolve_agent_model's 4-level priority for the --effort lever, and
adds:
  - validation: a value outside {low,medium,high,xhigh,max} is dropped -> ""
  - flag assembly: --model / --effort / --fallback-model are present/absent in
    the built command exactly when the resolved value is non-empty.
