- Added support for cross-compilation via CARGO_BUILD_TARGET environment variable, enabling builds for non-native targets like ARM64 Linux.
- Added support for overriding platform and architecture detection via TARGET_PLATFORM and TARGET_ARCH environment variables.
- Modified native build script to search for release artifacts in target-specific directories when cross-compiling.
- Updated CI workflow to use cross-compilation toolchain for ARM64 Linux builds instead of native ARM64 runners.
- Created comprehensive porting guide documenting how to port hot paths to pi-natives with anatomy, checklist, and troubleshooting sections.
