Add automated release pipeline with cross-platform builds

Implements comprehensive release automation using GitHub Actions and GoReleaser
to streamline the distribution process and provide cross-platform binaries:

• Add GitHub Actions workflow for automated releases triggered by version tags
• Configure GoReleaser for cross-platform builds (Linux/macOS on amd64/arm64)
• Set up Homebrew tap integration for easy package installation
• Enable draft releases with automatic changelog generation
• Inject version metadata (version, commit, date) into binaries during build
• Create archives with documentation and checksums for distribution
