[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.

Start by locating the existing hasCount assertion implementation and the Playwright polling infrastructure used to retrieve element counts. Check how comparable assertions expose greater-than, less-than, at-least, and at-most conditions. Done means the proposed methods support threshold checks with native polling and improve readability over negated equality checks.
