⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: uv.lock

Command failed: uv lock --upgrade-package mypy
Using CPython 3.14.7 interpreter at: /opt/containerbase/tools/python/3.14.7/bin/python3
  × No solution found when resolving dependencies for split (markers:
  │ python_full_version == '3.9.*' and sys_platform != 'darwin'):
  ╰─▶ Because the requested Python version (>=3.9) does not satisfy
      Python>=3.10 and mypy==2.3.1 depends on Python>=3.10, we can conclude
      that mypy==2.3.1 cannot be used.
      And because only mypy<=2.3.1 is available, we can conclude that
      mypy>=2.3.1 cannot be used.
      And because activations-plus:dev depends on mypy==2.3.1 and your project
      requires activations-plus:dev, we can conclude that your project's
      requirements are unsatisfiable.

hint: While the active Python version is 3.14, the resolution failed for other Python versions supported by your project. Consider limiting your project's supported Python versions using `requires-python`.
hint: The `requires-python` value (>=3.9) includes Python versions that are not supported by your dependencies (e.g., mypy==2.3.1 only supports >=3.10). Consider using a more restrictive `requires-python` value (like >=3.10).
