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.
Add a repository .editorconfig and a root eslint.config.ts to standardize formatting and linting. Migrate packages/webui ESLint config to TypeScript (eslint.config.ts) with project-specific rules and tsconfigRootDir handling, and remove the old JS config. Update package.json to run ESLint directly (add lint and lint:fix) and add required ESLint/dev dependencies; also add jiti to packages/webui/package.json. Include a small formatting tweak to tsconfig.base.json.
