fix: resolve GitHub Actions build failures and optimize cross-compilation

- Remove invalid github-token parameter from arduino/setup-protoc action
- Fix cross-compilation RUSTFLAGS issue by conditionally setting target-cpu=native
- Update workflow tag triggers from v* to * for non-v prefixed tags
- Optimize Zig and cargo-zigbuild installation using official actions

This resolves build failures in aarch64-unknown-linux-musl target where
zig was receiving invalid x86_64 CPU flags during cross-compilation.
