⚠ 26 problems (0 errors, 26 warnings)

Warnings:
  26  cognitive-complexity  

It looks like these warnings were not getting noticed or fixed.

What is changed and how it works?

This PR:

1. Changes the complexity limit to 100 and marks existing cases that go over 100 with //revive:disable.
2. Changes the check to error when the limit is exceeded (previously it would just warn)

This makes accidentally exceeding this with new code harder.
