Function ocfDeepEqual

ocfDeepEqual(a: unknown, b: unknown): boolean
Deep equality comparison for OCF objects with normalization.

This comparison:
- Normalizes numeric strings to fixed precision
- Treats empty arrays/objects as equivalent to undefined
- Trims string whitespace
- Recursively compares nested objects
Parameters
- a: unknown
  First OCF object
- b: unknown
  Second OCF object
Returns boolean
True if objects are semantically equal
Example
```
  const obj1 = { quantity: '100.0000000000', name: 'Test' };
  const obj2 = { quantity: '100', name: 'Test' };
  ocfDeepEqual(obj1, obj2); // true - normalized numbers match
  
```
