feat: Build & Upload cross-platform binaries as artifacts

[KKimj]

First of all, thanks for maintaining this great library! ..

✨ Changes

Ref: https://docs.deno.com/runtime/reference/cli/compile/#supported-targets

• Added cross-platform builds
  • x86_64-unknown-linux-gnu
  • aarch64-unknown-linux-gnu
  • aarch64-apple-darwin
  • x86_64-apple-darwin
  • x86_64-pc-windows-msvc
• Upload artifacts per target
  • Each platform binary is now uploaded as a separate artifact
  • Makes it easier for contributors to download only what they need

📸 Tests

Manually tested via workflow_dispatch:

💡 Further Considerations

• macOS Universal build
  Could simplify distribution, but results in a much larger file size (~2×).
• Windows ARM64 build
  Could be added later if there's interest — Deno supports cross-compilation.

📝 Notes

• Builds finish in ~30–35 seconds
