- Built the generic Windows release binary with Bun's baseline x64 runtime so older Windows 10 CPUs do not hit the AVX2-only modern executable.
- Forced pi-natives release builds to link PCRE2 statically so macOS installs do not depend on Homebrew's libpcre2 dylib.
- Added release dry-run and native-build regression coverage for the portable artifact contracts.
