Add Agent QA testing prompt

[pranshuchittora]

Summary

Add a concise Jules testing prompt for authoring and documenting an Agent QA web regression suite.

Why it fits

The catalog's Testing section already covers unit, integration, compatibility, network, and fixture tasks. This prompt adds a product-level black-box user journey while preserving the repository's prompt-plus-sub format.

Agent QA supports natural-language web and mobile regression suites with persistent test memory. The prompt asks Jules to make a concrete repository change and document the run path; it does not claim a native Jules integration or replace the project's existing code-level tests.

Agent QA currently requires Node.js 24 or newer. Its FSL-1.1-ALv2 license is source-available rather than OSI open source and converts to Apache-2.0 after two years. I am affiliated with Vostride and Agent QA.

Validation

• git diff --check passes.
• The prompt is concise, appears under Testing, uses inline-code formatting, and includes the required explanatory sub line.
• Standard awesome-lint reports 61 repository-wide errors caused by the catalog's prompt-list structure; the added prompt produces no diagnostic.
• The canonical Agent QA URL returns HTTP 200.
• The README, issues, and pull requests contain no existing Agent QA entry or proposal.
