Make line endings deterministic across macOS, Windows, and Linux while preserving the native checkout format required by Windows launchers.
Pin the tested application runtime and Node type baseline, add a shared startup preflight, and keep independently published packages on their existing compatibility ranges.
Align local scripts, pull request validation, complete package builds, dependency metadata, and contributor documentation around the same Node and pnpm contract. The root test command now covers every tested workspace package while a focused Core command remains available for local iteration.
Restructure GitHub Actions to build Windows and Linux matrix targets and produce platform-specific artifacts.
- .github/workflows/dev-build.yml: split cleanup/build jobs, add matrix (win-x64, linux-x64), set SNOWLUMA_TARGET for builds, produce full and -lite archives (.zip on Windows, .tar.gz on Linux), unify upload step and ensure errors when artifacts missing.
- .github/workflows/release.yml: convert release build to matrix, produce platform archives, download/collect artifacts, generate multi-platform release notes (bash), and create the GitHub release with both .zip and .tar.gz assets.
- packages/core/vite.config.ts: add fs import and SNOWLUMA_TARGET handling, pick platform-specific runtime files (launcher.bat or launcher.sh), enumerate native files per target, fail CI if expected native binaries are missing, and copy native files into dist/native.
- packages/runtime/launcher.sh: add a portable launcher for Linux that prefers a bundled node binary or falls back to PATH and execs index.mjs.
These changes enable cross-target CI packaging and enforce that native binaries are present before releasing.
