Reproduction for jdx/mise#5665

Context

Using mise + uv in GitHub workflows with automatic Python virtualenv activation doesn't work. Running python causes the workflow hangs and memory leak.

This is just a simple reproduction by running python, in the actual use case other uv related commands were run and failed.

Current behavior

The step python --version in .github/workflows/mise.yaml hangs and got killed eventually.

When running remotely on GitHub, the step failed with exit code 143 (run).

When running locally with act (through GitHub Local Actions in VSCode), the log has a bit more information as shown below, and the Docker container reached the memory limit and got OOMKilled.

⭐ Run Main python --version
  🐳  docker exec cmd=[bash -e /var/run/act/workflow/4] user= workdir=
mise ERROR /opt/hostedtoolcache/uv/0.7.21/x86_64/uv failed
mise WARN  uv venv failed: /opt/hostedtoolcache/uv/0.7.21/x86_64/uv exited with non-zero status: no exit status
Python 3.13.5
  ✅  Success - Main python --version [4m5.44525175s]

Expected behavior

mise automatically activates uv virtualenv without any issues.
