Function createSeededRandom

createSeededRandom(seed: number): () => number
Creates a random source that repeats — the same seed always produces the same sequence.
Parameters
- seed: number
  Any integer. Distinct seeds give unrelated sequences.
Returns () => number
A function returning a number in [0, 1), drop-in for Math.random.
Remarks
Values carry the full 53 bits of a double, as Math.random does.

Each value comes from the position in the sequence, so a caller reproduces its values only by asking in the same order. Where the order is not fixed, key the draws instead (keyedRandom).

Not a cryptographic source — never use it for keys, tokens or identifiers.
Example
```
const next = createSeededRandom(42);
next(); // 0.6011037487409305, every time
```
