The documented import for `assert_output_satisfies` raises `ImportError`

[ambiorix2099]

Bug Description

The import shown in semantic.py's own module docstring fails.

Root Cause

src/conductor/ai/agents/testing/semantic.py:9 documents
from conductor.ai.agents.testing import assert_output_satisfies, but testing/__init__.py
never imports semantic and the name is absent from __all__ (__init__.py:61-97).

Steps to Reproduce

python -c "from conductor.ai.agents.testing import assert_output_satisfies"
# ImportError

Expected Behavior

Either add the re-export or correct the docstring. The re-export looks like the intent, since
every other assertion in the package is exposed that way. Working import today is
from conductor.ai.agents.testing.semantic import assert_output_satisfies.

Additional Notes

Verified against origin/main @ c99e2cf9. Found while reading the module; unrelated to the
tool-call and event defects filed separately.
