Fix GitHub Actions workflow to produce functional artifacts

[Copilot]

The GitHub Actions workflow for building GateSwitchWay was producing artifacts that were non-functional due to several critical issues. This PR fixes all identified problems to ensure the built executables work correctly on target Windows systems.

Issues Fixed

1. Workflow Filename Typo

The workflow file was incorrectly named publush.yml instead of publish.yml, which could cause confusion and maintenance issues.

2. PowerShell Version Detection Bug

The version detection logic had a critical flaw:

# Before (broken) - returns "True" when git command fails
$version = $(git describe --tags --abbrev=0) -or "0.0.0"

# After (fixed) - properly handles errors and returns fallback
try {
    $version = git describe --tags --abbrev=0 2>$null
    if ($LASTEXITCODE -ne 0) {
        $version = "0.0.0"
    }
} catch {
    $version = "0.0.0"
}

This was causing executables to be named GateSwitchWay-True.exe instead of GateSwitchWay-0.0.0.exe.

3. Build Tool Compatibility Issues

The workflow was using dotnet-warp which has known compatibility issues with Windows Forms applications that require administrator privileges. This often results in executables that fail to run or have missing dependencies.

4. Missing Self-Contained Configuration

The published artifacts weren't truly self-contained, potentially missing required .NET runtime components or native libraries.

Technical Solution

Replaced the dotnet-warp approach with native .NET single-file publishing:

dotnet publish GateSwitchWay.csproj \
  --configuration Release \
  --runtime win-x64 \
  --self-contained true \
  --output "publish" \
  -p:PublishSingleFile=true \
  -p:IncludeNativeLibrariesForSelfExtract=true \
  -p:PublishTrimmed=false \
  -p:AssemblyName="GateSwitchWay-$version"

Key improvements:

• Self-contained: Includes all .NET runtime dependencies
• Single file: Packages everything into one executable
• Native libraries: Includes Windows-specific dependencies for network configuration
• No trimming: Prevents reflection issues common with Windows Forms applications
• Proper naming: Uses correct version in the executable name

Validation & Quality Assurance

Added comprehensive validation steps to catch build failures early:

• Project structure verification
• Compilation success checks
• Artifact creation validation
• File size and metadata reporting
• Clear error messages and user instructions

Expected Results

The workflow now produces:

• Functional executables that run properly on Windows systems
• Self-contained artifacts requiring no additional .NET installation
• Properly named files using correct version detection
• Clear user instructions for downloading and running the application
• Comprehensive error reporting when builds fail

Users can now download artifacts from GitHub Actions and run them directly on Windows systems (with administrator privileges) without any additional setup or dependency installation.
