a2a-bridge v0.2.1

Fixed

• Containerized and already-logged-in Codex agents can declare pre_authenticated = true, preventing
  the bridge from re-invoking codex-acp's interactive ChatGPT browser login before session/new.
  Shipped Codex configs now use the setting, restoring gpt-5.6-sol model/effort selection and prompt
  turns with codex-acp 1.1.2 in browserless containers.
