Current logging/model context can still leak sensitive query/fragment data (e.g., page URL not redacted and raw Error objects may still contain full URLs), and the new redaction paths in alt-text-quality lack targeted test coverage.
Pull request overview
This PR introduces a shared URL-redaction helper to prevent URL query strings/fragments (e.g., signed CDN tokens) from being sent to the model context or written into CI logs, and applies it to the alt-text-quality rule’s link context and error logging.
Changes:
- Add
redactUrl()utility to strip query strings and fragments with a safe fallback for non-parseable URLs. - Update
alt-text-qualityto redact linkhrefvalues and the image URL interpolated intoconsole.errormessages. - Add unit tests for
redactUrl().

I suggest leaving a comment here about why this regex is here, we probably won't recall down the line :)

even better, I wonder if using redactUrl directly on the String cast would work? 🤔

Follow-up to #38.
Builds on the bot's href redaction catch and extends it: pulls the href plus the two console.error image-URL logs in evaluate() (which leak the same querystring data into CI logs) into one reusable redactUrl() helper. Keeps the original link/button wording, the rewording in the bot's inline suggestion is a separate concern.
