Update uv.lock to fix uv sync with Python 3.14

[loganrosen]

uv sync currently fails in the mcp module with the following:

> uv sync --all-extras
  × No solution found when resolving dependencies for split (markers: python_full_version >= '3.14'):
  ╰─▶ Because there is no version of llvmlite{python_full_version >= '3.14'}==0.46.0b1 and shap==0.50.0 depends on llvmlite{python_full_version >= '3.14'}==0.46.0b1, we can conclude that shap==0.50.0 cannot
      be used.
      And because bugbug==0.0.616 depends on shap[plots]==0.50.0 and only bugbug==0.0.616 is available, we can conclude that all versions of bugbug cannot be used.
      And because your project depends on bugbug and your project requires bugbug-mcp[llms-txt], we can conclude that your project's requirements are unsatisfiable.

      hint: `llvmlite` was requested with a pre-release marker (e.g., llvmlite==0.46.0b1), but pre-releases weren't enabled (try: `--prerelease=allow`)

      hint: While the active Python version is 3.12, the resolution failed for other Python versions supported by your project. Consider limiting your project's supported Python versions using
      `requires-python`.

There are two options: (1) restrict the mcp module to Python versions less than 3.14, or (2) allow pre-release versions of dependencies. We need to do one of these until shap releases a new version containing this change. I chose (2) to allow use of the module with Python 3.14, but please let me know if you prefer (1).

I ran uv sync --prerelease=allow to generate this change. That triggered it to ignore the current lockfile and update the dependencies to the latest compatible versions.
