fix: address CodeRabbit review feedback in linkDetector

- Fix double mailto: prefix for mailto: URLs in linkToken() — values
  starting with "mailto:" are now classified as "url" not "email"
- Support schemeless URLs with ? or # suffixes (e.g. example.com?x=1,
  example.com#frag) in both SCHEMELESS_RE and isSingleUrl()
