[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.

まず、既存の hasCount アサーションの実装と、要素数の取得に使用されている Playwright のポーリング基盤を見つけます。比較可能なアサーションが、より大きい、より小さい、以上、以下の条件をどのように公開しているかを確認します。提案するメソッドがネイティブポーリングによるしきい値チェックをサポートし、否定した等価性チェックよりも可読性を向上させれば完了です。
