[Feature]: Numerical Comparison Assertions for hasCount

🚀 Feature Request

Currently, assertThat(locator).hasCount(n) only supports strict equality. In many real-world testing scenarios, the exact number of elements is dynamic, and we only need to verify if the count meets a certain threshold (e.g., "at least one item is present" or "no more than 10 items").

Example

Proposed Methods: hasCountGreaterThan(int n), hasCountLessThan(int n), hasCountAtLeast(int n), hasCountAtMost(int n).

Motivation

Improved Readability: Replaces less intuitive workarounds like assertThat(locator).not().hasCount(0).
Native Polling: These checks would leverage Playwright’s built-in auto-waiting mechanism, making tests much more stable than manual polling loops.
Implementation: The implementation is straightforward as Playwright already has the infrastructure to retrieve element counts and poll for conditions. It simply requires adding comparison operators to the assertion logic.

Comienza localizando la implementación existente de la aserción hasCount y la infraestructura de polling de Playwright utilizada para obtener los recuentos de elementos. Comprueba cómo las aserciones comparables exponen condiciones de mayor que, menor que, al menos y como máximo. Se considera terminado cuando los métodos propuestos admiten comprobaciones de umbral con polling nativo y mejoran la legibilidad frente a las comprobaciones de igualdad negadas.
