- Capitalize first letter of all description comments
- Add trailing periods to comment sentences
- Replace `e.g.` with `Example:` for consistency
- Convert inline URLs to `See: [description](url)` format
- Move inline comments before config keys
- Add ` #` suffix to group separator comments
- Fix `available values` to standalone lines
- Wrap angle brackets in backticks for syntax examples
