Pull Request

Description

Establishes BuildMark repository following the SarifMark pattern: multi-target .NET tool (.NET 8/9/10, C# 12), comprehensive CI/CD pipelines, linting infrastructure, and GitHub templates.

Key Components:

• Project structure: Console application with --version and --help commands, MSTest project, solution file
• Linting: cspell, markdownlint, yamllint, editorconfig with file-scoped namespaces and naming conventions
• CI/CD: Reusable build workflow (quality checks, multi-OS builds, CodeQL, integration tests), push trigger, release workflow with NuGet publish
• GitHub templates: Issue forms (bug/feature), PR checklist, custom agent specifications (documentation-writer, project-maintainer, software-quality-enforcer)
• Quality: TreatWarningsAsErrors, Microsoft.CodeAnalysis.NetAnalyzers, SonarAnalyzer.CSharp, SBOM generation
• License: MIT

Type of Change

• Icon.png
• src folder with application (just hello world for now)
