Add test fixture for non-collaborative (file-based) code path

This PR introduces a new test fixture to exercise the non-collaborative (file-based) execution path for Jupyter cell mutation tools, addressing the gap described in issue #224.

Key changes:

• Added jupyter_server_no_collab fixture to start Jupyter without collaboration enabled.
• Extended test parametrization to include a new mode: jupyter_extension_no_collab.
• Updated test logic to correctly handle tool availability differences between collaborative (YDoc) and non-collaborative modes.

Yea tests/test_otel_integration.py seems to be failing in the CI, although it passes locally when I run the tests. I will take a closer look.

The failures are due to some awkwardness of the otel-related test harnesses. @emekaokoli19 chances are you were probably testing against some intermediate version, with otel feature added with partial test coverage or something. I have reworked the test harnesses to let otel and non-collaborative tests coexist, my version is here -- abbbe#4. Unfortunately, I saw no easy way to fix it and keep the test suite clean and legible, so changes are quite extensive... Unless you have better ideas, feel free to merge into your branch & tests or whatever.
