feat: add musl linux builds

[QuiiBz]

Closes #131

Add new musl linux builds for x86 and arm64, as we are not statically linking dependencies (because it would bloat the size of the binary): #131 (comment)

The gnu binaries keep the same NPM package name for backward compat sherif-linux-x64 / sherif-linux-arm64, but we have two new variants for musl sherif-linux-x64-musl / sherif-linux-arm64-musl. The GitHub release binaries already end with -gnu so for those, we also simply add new -musl variants and update the GitHub Action to prefer musl if required

Pull Request Overview

This PR adds support for musl-based Linux distributions (such as Alpine Linux) by introducing dedicated musl binaries alongside the existing glibc binaries. The implementation includes runtime detection of the libc variant and automatic fallback mechanisms.

• Adds musl libc detection logic using dynamic linker presence checks
• Introduces musl-specific binary variants for both x64 and arm64 Linux architectures
• Updates build and release workflows to produce and publish musl binaries
