⚠️ 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 python
Using CPython 3.14.2 interpreter at: /opt/containerbase/tools/python/3.14.2/bin/python3.14
warning: Resolving despite existing lockfile due to fork markers being disjoint with `requires-python`: `python_full_version >= '3.10' and python_full_version < '3.14'` vs `python_full_version == '3.14.*'`
  × No solution found when resolving dependencies:
  ╰─▶ Because onnxruntime==1.23.2 has no wheels with a matching Python version
      tag (e.g., `cp314`) and only the following versions of onnxruntime are
      available:
          onnxruntime<=1.23.2
          onnxruntime>1.24.dev0
      we can conclude that onnxruntime>=1.23.2,<1.24.dev0 cannot be used.
      And because your project depends on onnxruntime>=1.23.2,<1.24.dev0, we
      can conclude that your project's requirements are unsatisfiable.

      hint: Wheels are available for `onnxruntime` (v1.23.2) with the
      following Python ABI tags: `cp310`, `cp311`, `cp312`, `cp313`, `cp313t`

      hint: `onnxruntime` was requested with a pre-release marker (e.g.,
      onnxruntime>1.23.2,<1.24.dev0), but pre-releases weren't enabled (try:
      `--prerelease=allow`)
