Enable github actions with binaries and deb pkg

[vicendominguez]

This PR adds GitHub Actions workflows to:

• Build cross-platform Go binaries (Linux/Darwin/Windows, amd64/arm64) for releases
• Package the Linux amd64 binary into a Debian package (.deb)
• Automatically upload artifacts to GitHub Releases on tag creation

Key features:

• Uses matrix strategy for efficient multi-arch builds
• Excludes Windows/ARM64 (unsupported combination)
• Includes proper version tagging via ldflags
• Creates installable Debian package with proper metadata
• Only triggers on release tags

The workflow will automatically build, package, and release assets when new tags are pushed.
