Integrate PowerShell Script for Stable and Fast Communication with Windows OpenSSH ssh-agent from WSL2

[masahide]

The primary focus of this pull request is the integration of a PowerShell script to enable stable and fast communication between the WSL2 environment and the Windows OpenSSH ssh-agent. This significant change has led to several other related updates and improvements:

1. PowerShell Script Integration:

   • Introduced a new PowerShell script pwsh.ps1, embedded within the Go script, which handles packet reading, writing, and interaction with the named pipe client stream for communication with the Windows OpenSSH ssh-agent. This integration is crucial for ensuring reliable and efficient communication from WSL2.

2. New Go Script:

   • Added a new Go script main.go under cmd/wsl2-ssh-agent-proxy/. This script manages the core logic for the WSL2 SSH Agent Proxy, including socket handling, packet multiplexing, and the integrated PowerShell script execution.

3. GitHub Actions Workflow:

   • Updated the GitHub Actions workflow to use the latest versions of various actions, such as actions/upload-artifact@v4, actions/checkout@v4, actions/setup-go@v5, and actions/download-artifact@v4.
   • Added a new job build-wsl2-ssh-agent-proxy to build the WSL2 SSH Agent Proxy. This job compiles the Go code for the WSL2 SSH Agent Proxy and compresses the output for later use.

4. Release Process:

   • Updated the release process to include artifacts generated by the new build job build-wsl2-ssh-agent-proxy.

These changes collectively enhance the project’s ability to facilitate a more robust and high-performance communication channel between WSL2 and the Windows OpenSSH ssh-agent, improving the overall user experience in such environments.

The wsl2-ssh-agent-proxy is an alternative to socat and omni-socat, serving as an ssh-agent proxy that runs persistently on the WSL2 side.
