GitHub Action Marketplace listing and installer-test hygiene.

• Action name is battest Action with branding (check-square, blue).
• Installer tests assert the parsed GitHub asset-host allowlist and URI host
  check. The regex timeout test builds its nested-quantifier pattern at
  runtime so CodeQL does not treat those fixtures as URL sanitizers or a
  shipped ReDoS expression.
