Pull Request Overview
This PR introduces a dual-build system for oxlint's JavaScript/TypeScript code, generating both release and debug builds. The debug build enables runtime assertions through a DEBUG global constant, while the release build optimizes away debug-only code.
Key changes:
- Debug builds generated alongside release builds with
DEBUG: 'true'defined, enabling runtime checks inassertIsNonNulland similar functions - Tests configured to run against debug builds to catch assertion failures during development
- Build infrastructure updated to output debug builds to a separate
/debugdirectory (excluded from NPM packages)

Generate a debug build, in addition to the normal release build. In the debug build, `DEBUG` global is defined as `true` and `assertIsNonNull` does a runtime assertion. In release build, `DEBUG === false` and minifier removes debug-only code. Run the tests in debug mode. Debug build is generated in a separate directory from `dist`, so is *not* included in NPM package.

#15949) #15921 added a debug build for Oxlint, and various PRs since have tweaked it. However, I now realize there's little point in generating *both* a release build and debug build. Just create one build, and use env var `DEBUG` to control whether it has debug assertions included in it or not. `pnpm run build` produces release build with no debug assertions, `pnpm run build-test` includes the asserts. I've verified that both do what they're meant to.
