Add GitHub Actions build workflow for .NET 10 only

[Copilot]

Adds CI build configuration for the solution in src/ folder, building exclusively for .NET 10 target frameworks.

Implementation

• Workflow: Runs on windows-latest, triggers on push/PR to main
• SDKs: Installs .NET 10.0.x only
• Build strategy: Uses MSBuild /p:TargetFrameworks parameter to override project targets per build

Target Frameworks

Each project builds for .NET 10 only (excluding all older framework versions):

# Standard projects
/p:TargetFrameworks="net10.0"

# SystemDrawing (Windows-specific)
/p:TargetFrameworks="net10.0-windows"

Projects built: DocSharp.Binary.* (Common, Doc, Xls, Ppt), DocSharp.Common, DocSharp.Docx, DocSharp.Markdown, DocSharp.ImageSharp, DocSharp.SystemDrawing

Original prompt

Add github actions build config to https://github.com/stesee/DocSharp primary building solution in "src" folder. Elide builds of that dont target .net 10.

@copilot you got it wrong: include. Net 10. Exclude others

Fixed in commit 4d36283. The workflow now builds ONLY for .NET 10 targets (net10.0 and net10.0-windows), excluding all older framework versions.

Pull request overview

This PR adds a GitHub Actions CI workflow to build the DocSharp solution targeting .NET 10 exclusively. The workflow uses MSBuild parameters to override the multi-targeted project files to build only for .NET 10, avoiding older framework versions.

Key Changes:

• Adds new GitHub Actions workflow triggered on push/PR to main branch
• Configures Windows-based builds using .NET 10.0.x SDK
• Builds 9 projects individually with framework override parameters

The workflow restores dependencies once but then builds each project individually. This approach is inefficient because each individual build command will implicitly restore dependencies again. Consider either:

1. Using --no-restore flag on the build commands after the initial restore
2. Or removing the separate restore step and letting the first build command handle restoration

This will significantly speed up the CI build process.

Building each project individually is verbose and error-prone. The build will not fail fast if an earlier project fails, making it harder to identify build issues. Consider building the solution file instead with the TargetFrameworks override:

dotnet build src/DocSharp.sln --configuration Release --no-restore /p:TargetFrameworks="net10.0"

This single command would build all projects that support net10.0, and for DocSharp.SystemDrawing (which requires net10.0-windows), you could add a separate solution-level build command or continue to build it individually.
