run_shell_command tool hangs when running pwsh.exe in WSL2

[Loongphy]

What happened?

When using the CLI's shell tool within a WSL2 environment to execute pwsh.exe --version, the process hangs indefinitely.

There is no output to stdout or stderr.

What did you expect to happen?

The CLI should successfully execute the command and immediately stream the output to the terminal.

For example, running pwsh.exe --version should display the version string and return control to the user immediately.
