Function normalizeKey

normalizeKey(token: string): string
Normalizes a single binding token (e.g. "UpArrow", "Esc", "A") to the lowercased KeyboardEvent.key value it should match. Unknown tokens map to their own lowercased form.
Parameters
- token: string
  A raw key token from a binding string.
Returns string
The normalized key, comparable against a lowercased event.key.
Example
```
normalizeKey("UpArrow"); // "arrowup"
normalizeKey("Esc");     // "escape"
normalizeKey("A");       // "a"
```
