v8.1.0

Changed

• Bumped the maintained htmlcut-core dependency to 10.2.0, removed FFHN's
  temporary workspace-root servo_arc and tendril overrides, and now rely on
  HTMLCut's shipped downstream-safe selector/parser stack instead of carrying a
  local release-gap patch layer.
• FFHN no longer parses CSS selectors through scraper during target validation; it now
  validates CSS-selector and delimiter-pair contracts through HTMLCut's interop plan surface
  so the contract check matches the upstream execution stack FFHN actually runs.

Fixed

• The maintained FFHN-to-HTMLCut strict-provenance proof now exercises both a CSS-selector
  target and a delimiter-pair target against the shipped htmlcut-core v10.2.0
  dependency graph, and the maintainer docs/NOTICE now describe that upstream
  ownership truthfully instead of pointing at removed FFHN-local patch overrides.
