- Standardized `fastembed` and `onnxruntime-node` as external dependencies for all compiled binaries.
- Removed manual exclusion logic from individual build scripts in favor of a centralized configuration.
- Updated release build dry-run output to reflect consistent external dependency handling.
Fixes#5195
- 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.
Fixes#5172
