Summary

Follow-up to #26 to further clean up the array parameter documentation output:

• Strip trailing { from array parameter descriptions (e.g., $args { → $args)
• Increase search window from 50 to 100 tokens to capture full array arguments in code snippets
• Don't output empty parameter descriptions

Example output

## Parameters

- *`array`* `$args`
  - *`string`* `$name` Term name.
  - *`string`* `$slug` Term slug.
  - *`int`* `$parent` Parent term ID.

See multiple_type_tags_hook for a live example.
