Introduce testing engine along with test schema

[mohammed90]

Given the time shortage and absence of feedback and brain gatherings, I, shamefully, turned to GitHub Copilot. The output is yet to be thoroughly reviewed. I'm putting it out for the world and will circle back later.

Pull request overview

This PR introduces a comprehensive HTTP compliance testing framework generated primarily by GitHub Copilot. The implementation includes four Go-based tools: a test case generator, a server test engine, a client test engine, and an HTML report generator, along with supporting JSON schemas and documentation.

Key additions:

• Test case generation from RFC requirements with automatic test type inference
• Server compliance testing engine with HTTP request/response validation
• Client compliance testing engine with mock server capabilities
• HTML report generator with interactive dashboard and search functionality

[nitpick] Embedding a 600+ line HTML template as a string constant makes the code difficult to maintain. Consider moving the HTML template to a separate file and using embed.FS or reading it at runtime. This would improve code organization and make the template easier to edit and test.

The HTTP client does not disable redirect following, which could cause issues for tests that expect specific behavior. Consider adding a custom CheckRedirect policy to control redirect behavior explicitly: client.CheckRedirect = func(req *http.Request, via []*http.Request) error { return http.ErrUseLastResponse } to prevent automatic redirect following if the test needs to validate redirect responses.
