ISSUES CLOSED: #5566
Add BDD tests to verify that cleveragents.acp is not importable and
the acp directory does not exist in the source tree. This ensures v3.6.0
deliverable #1 compliance: 'No acp references in public API'.
The acp module was renamed to a2a in issue #688, but stale __pycache__
files were left behind, allowing the module to still be imported from
bytecode. This test ensures this compliance persists.
