pdm==2.26.4[locked] causes sqlite3.OperationalError: database is locked

[bombaci-vsc]

Describe the bug

Using the GitHub action pdm-project/setup-pdm@v4 on Windows to install pdm can result in syncs that can fail with the error: sqlite3.OperationalError: database is locked

Here are the logs of a failed job, including additional debug if the installed pdm virtual environment: https://github.com/bombaci-vsc/sarkit/actions/runs/21015958166/job/60421036467

The symptoms seem to be the same as #3719. However the setup-pdm action doesn't provide an easy way change the installed version of hishel.

setup-pdm@v4 installs pdm[locked], which as of 2.26.4 depends on hishel==1.1.7.

To reproduce

1. Use a GitHub Windows runner
2. Use pdm-project/setup-pdm@v4 to install pdm 2.26.4
3. Run pdm lock; pdm sync;

Expected Behavior

pdm sync completes without error
