fix: page advisor lint results

[ahfoysal]

What

Adds optional limit and offset inputs to get_advisors so large advisor responses can be fetched in smaller chunks.

This keeps the existing behavior unchanged when pagination options are omitted, but when either option is provided the returned lints array is sliced and a small pagination object is included with total, offset, limit, and next_offset when another page exists.

Fixes #124.
