Changes

• Preserve accessibility rules and valid elements when a selector exceeds the report limits. Count omitted elements in scan coverage.
• Keep scan progress available to assistive technology during the request. Cover progress, cancellation, and completion in browser checks.
• Remove the unused HTML capture module from the scanner and Docker build context.

Verification

• App tests, report serializer tests, Docker fixture tests, and both app builds passed.
• Scanner images rebuilt. Controlled browser checks passed in Chromium, Firefox, and WebKit on rerun.
• Both npm dependency audits reported zero vulnerabilities.
