fix: Remove extra closing brace breaking if/else chain

Remove stray closing brace at line 3127 that was breaking the if/else chain
before the 'else if (prop.enum)' branch, causing 'Unexpected token else'
syntax error.

Problem:
- Extra '}' at line 3127 closed the prop.type === 'array' block prematurely
- This broke the if/else chain, causing syntax error when parser reached
  'else if (prop.enum)' at line 3128
- Structure was: } else if (array) { ... } } } else if (enum) - extra brace

Solution:
- Removed the extra closing brace at line 3127
- Structure now correctly: } else if (array) { ... } } else if (enum)
- Verified with Node.js syntax checker - no errors
