EN：

1. Optimized the :collectMatcherEvidence function to collect four types of evidence: status_code, body contains, body matches, and header.
2. Added :header for precise matching of Content-Type in response headers.
3. To match Content-Type: text/plain; charset=utf-8 in the response header.
4. Example: #@ matcher: header["Content-Type"] contains "text"
5. Or: #@ matcher: header["Content-Type"] contains "text/plain"
