Continue preparing PR #481 for landing after the test and documentation commits were pushed. Follow the new CI run to completion and diagnose any failures.

git diff HEAD~1..HEAD -- tests/devx/test_debugger.py

Both macOS jobs failed while evaluating the new skipif marker. The expression returned the CI=true environment string instead of a boolean, so pytest evaluated true as Python source and raised NameError during test setup. Coerce _ci_env to bool so pytest receives a boolean marker condition on Darwin CI.

Verification should exercise the condition with CI=true and a simulated Darwin platform, then rerun the debugger/tooling TCP and UDS suites.
