Research direction

This issue requests formatting JSDoc comments to a consistent style. Start by examining the TypeScript language service's formatting infrastructure in src/services/formatting/. Look for existing formatting rules for comments and how they are applied. The original issue link (https://github.com/Microsoft/TypeScript/issues/11456) may contain additional context. Consider writing a simple formatter that normalizes JSDoc indent and spacing, integrating it into the language service's formatting pipeline.
