Harvest #3009 for the v0.8.59 release lane. Adds a paired Terminal-Bench harness for CodeWhale and Codex, a Codex Harbor adapter, generated-result ignore protection, and benchmark docs.
Maintainer amendments keep explicit zero-valued metrics, regenerate parent task names, write refreshed summaries in regenerate mode, and allow transcript paths outside the repo.
Fixes#2952.
