Summary by cubic

Sets Codex’s default model to gpt-5.3-codex and improves AWF startup error diagnostics; also standardizes report templates for better readability.

• New Features

  • Adds CodexDefaultModel (gpt-5.3-codex) and uses it when GH_AW_MODEL_AGENT_CODEX/GH_AW_MODEL_DETECTION_CODEX are unset.
  • Updates Codex workflows to default GH_AW_INFO_MODEL, GH_AW_MODEL_AGENT_CODEX, and GH_AW_MODEL_DETECTION_CODEX to gpt-5.3-codex.
  • Refreshes tests and goldens to reflect the new fallback and keep fixtures stable.
  • Report templates: enforce h3+ headers and wrap long sections in <details>; A/B advisor doc adds the same guidance.

• Bug Fixes

  • actions/setup/js/handle_agent_failure.cjs now captures AWF startup failures and dependency errors (e.g., “[ERROR] Failed to start …”, “dependency failed to start: …”) and filters noisy wrapper lines; adds tests to cover these cases.
