Function map

map<T, U, E>(result: Result<T, E>, fn: (value: T) => U): Result<U, E>
Transform the Ok value, passing Err through unchanged. Dual-form: call data-first or curried (for use with pipe).
Type Parameters
- T
- U
- E
Parameters
- result: Result<T, E>
- fn: (value: T) => U
Returns Result<U, E>
Example
```
map(ok(2), (n) => n * 3);          // Ok 6 — data-first
pipe(ok("x"), map((s) => s.length));// Ok 1 — curried
```
