Improve Type performace

We have revised the method for extracting search parameters from paths.

Let's take a simple example to illustrate this. Suppose we have the following path string literal type:

type Path = '/products/?size&color';

Previously, we handled search parameters in the same way as path parameters. First, we split the path by /:

type Separated = ['', 'products', '?size&color'];

Then, we extracted the segment starting with ? as the search parameter:

type SearchParamField = 'size&color';

However, this approach was inefficient. Unlike path parameters, search parameters always appear at the end of the path. Therefore, we changed our approach to split the path string into the portion starting with /? and the rest.

type FindSearchParamField<T> = T extends `${infer Head}/?${SearchParamField}` ? SearchParamField : T;

type SearchParamField = FindSearchParam<Path>;
// ^
// 'size&color'
