I want to fix GeometryProcessSettings type not including its comments in index.d.ts but don't know how to

[agviegas]

The comments don't make it into index.d.ts because they're written as /* */ and // comments. TypeScript's declaration emit only keeps JSDoc /** */ comments. Switching each one above the GeometryProcessSettings members to /** */ will make them show up in dist/index.d.ts. No build config change needed.

I really wanted to add some tests to validate this change but was a bit discouraged since there is no test framework.

[agviegas]

Totally fair, that's on us. There's a half-wired jest setup but no real harness, and we've settled on moving to vitest (see the #197 thread). I'll get a minimal vitest config landed so fixes like this can ship with a test. This one's solid and already merged, so don't worry about it. Thanks for pushing, and the JSDoc tip is handled now in #226.
