feat: Add Windows support to retina-shell

[Copilot]

This PR adds Windows node support to retina-shell by:

1. Accepting Windows as a supported OS

   • Modified validation to accept both Linux and Windows nodes
   • Added a GetNodeOS helper function to detect node OS

2. Creating Windows-specific shell image

   • Added Dockerfile.windows with Windows networking tools
   • Added a Makefile target retina-shell-image-win to build Windows images

3. Windows pod manifests

   • Added Windows-specific configurations for hostProcess containers
   • Set Windows security context with appropriate user permissions
   • Handle Windows-specific file paths for filesystem mounting

4. CLI enhancements

   • Added a --windows-image-tag flag to specify Windows image variant
   • Auto-detect node OS and select appropriate image
   • Updated documentation and examples to include Windows usage

Example Usage

# Start a shell in a Windows node
kubectl retina shell winnode001

# Use specific Windows image variant
kubectl retina shell winnode001 --windows-image-tag windows-ltsc2019-amd64

Testing

Added unit tests for all new functionality including:

• Windows node validation
• Windows pod manifest generation
• OS-specific path handling

Fixes #1529.

Documentation updated in commit 3bce1e7. I've updated both the shell/README.md and docs/06-Troubleshooting/shell.md files to reflect Windows support, including examples, tools available, and environment variable configuration options.

I've run make fmt to apply formatting standards and added the GitHub Actions workflow job for the Windows retina shell image in commit b685638.

The changes include:

1. Added a new retina-shell-win-images job in .github/workflows/images.yaml that builds the Windows images using the retina-shell-image-win Makefile target
2. Updated the matrix configuration to build Windows images for both 2019 and 2022 LTSC versions
3. Added the new job as a dependency for the manifests job
4. Applied code formatting fixes to various files that were identified by make fmt

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.github.com
  • Triggering command: curl -s REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list

@copilot make this simpler by just using a host process container with only powershell installed

I've simplified the Windows shell container as requested in commit 04890c2. The changes include:

1. Removed all additional tool installations (WinDump, PortQry, Nmap)
2. Using just the built-in PowerShell that comes with Windows Server Core
3. Only relying on built-in Windows networking tools (ipconfig, netstat, ping, etc.)
4. Simplified the help text to show only the available built-in commands

This makes the Windows container much smaller and simpler while still providing the essential debugging capabilities.
