Pull Request Overview
This PR moves the Alpine/MUSL binary build process from the generic Linux build pipeline to a dedicated Docker-based pipeline using an Alpine container host. This ensures MUSL binaries are built in their native environment rather than cross-compiled.
Key changes:
- Introduces a new
LinuxMuslBuildstage with Alpine-specific build pipeline that uses Docker to build and extract native binaries - Refactors artifact paths in NuGet packaging to consume outputs from the new Alpine pipeline
- Adds improved logging and artifact inspection throughout the build process

PR Summary
This pull request introduces a new build pipeline for producing MUSL-based Linux binaries using Alpine, refactors the pipeline templates to support this build, and updates artifact handling to ensure correct packaging. The changes improve cross-platform support, streamline the build process for Alpine/MUSL, and ensure that the resulting native library is correctly extracted and included in the NuGet package.
