Function combine

combine<A, B>(a: A, b: B): Combined<A, B>
Performs a non-mutating deep merge of two or more values.
- All arguments are left unchanged; the result is always a new value.
- Objects are merged key by key; arrays are merged index by index.
- undefined values are skipped (they do not overwrite existing values).
- null values replace existing values.
Type Parameters
- A
- B
Parameters
- a: A
- b: B
Returns Combined<A, B>
A new deeply-merged value of the combined type.
Example
```
combine({ a: 1 }, { b: 2 }) // { a: 1, b: 2 }
combine({ a: { x: 1 } }, { a: { y: 2 } }) // { a: { x: 1, y: 2 } }
```
