fix(detect-duplicate): sanitize reposted issue titles

Security audit: the bot echoes other issues' titles back into a comment, so a
maliciously-named issue could ping (@everyone) or inject markdown/HTML. Break
@-mentions with a zero-width space and strip markdown/HTML control chars before
posting.
