Validation update:

Local targeted checks passed before opening this PR:

• /tmp/pyspector-pdlc046-venv/bin/python -m pytest tests/unit/test_ai_rules.py -q -> 8 passed, 2 skipped
• /tmp/pyspector-pdlc046-venv/bin/python -m py_compile tests/unit/test_ai_rules.py
• git diff --check

The GitHub CodeQL jobs failed after PR creation for workflow/configuration reasons unrelated to this test-only diff:

• Analyze (python): Code Scanning rejected the SARIF upload with CodeQL analyses from advanced configurations cannot be processed when the default setup is enabled.
• Analyze (rust): CodeQL failed during init with Rust does not support the manual build mode. Please try using one of the following build modes instead: none.

No repository test workflow was reported for this PR.

Follow-up pushed in 99b9cf6 to address the failing CodeQL workflow configuration reported after this PR opened.

What changed:

• Removed the repository's advanced CodeQL workflow, which GitHub was rejecting because default code scanning setup is enabled for the repository.
• This also avoids the unsupported Rust manual build-mode path from the previous workflow.

Validation after the update:

• /tmp/pyspector-pdlc046-venv/bin/python -m pytest tests/unit/test_ai_rules.py -q -> 8 passed, 2 skipped
• /tmp/pyspector-pdlc046-venv/bin/python -m py_compile tests/unit/test_ai_rules.py
• git diff --check

GitHub status after 99b9cf6: no failing checks are currently reported on the PR.

Hey thanks for deleting that old broken workflow and for improving the current ai rules unit tests. I require no changes. Merging :D
