Codex CLI 0.156.0-alpha.2 changelog - what changed

Under the hood

Added shared async backoff utilities to support steadier retry and timing behavior.
Extended exec-server noise-relay handling with clearer message framing.
Removed the JSONL-oriented exec event processor path in favor of the remaining output pipeline.
Dropped the exclude_slash_tmp configuration key from the recognized config surface.
Continued internal API and wire-model reshaping (thread resume and turn-steer responses, remote-control pairing, filesystem sandbox context, tool/user-input request shapes, and related payloads).
Routine lockfile and version metadata bump for the alpha channel.

If you still set exclude_slash_tmp in config, remove it; the key is no longer accepted.
