/**
* Provides locale-aware string filtering functions.
* Uses `Intl.Collator` for comparison to ensure proper Unicode handling.
*
* @param options - Optional collator options to customize comparison behavior.
*   See [Intl.CollatorOptions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/Collator/Collator#options) for details.
* @returns An object with methods to check if a string starts with, ends with, or contains a substring.
*
* @example
* const { startsWith, endsWith, contains } = useFilter();
*
* startsWith('hello', 'he'); // true
* endsWith('hello', 'lo'); // true
* contains('hello', 'ell'); // true
