Function Lazy

Lazy<Args extends readonly unknown[], Return>(
fn: (...args: Args) => Return,
opts?: ResolveOnceOpts,
): (...args: Args) => Return
Creates a lazy-evaluated version of a function that executes only once and caches the result.

The returned function will execute the original function on first call and return the cached result for all subsequent calls, regardless of arguments. This is useful for expensive computations or resource initialization.
Type Parameters
- Args extends readonly unknown[]
  The argument types of the function
- Return
  The return type of the function
Parameters
- fn: (...args: Args) => Return
  The function to make lazy
- Optionalopts: ResolveOnceOpts
Returns (...args: Args) => Return
A wrapped function that executes once and caches the result
Example
```
const getConfig = Lazy(() => {
  console.log('Loading config...');
  return { apiKey: 'secret' };
});

getConfig(); // Logs "Loading config..." and returns config
getConfig(); // Returns cached config without logging
```
