Merged PR #374, implementing issue #373, adds a bounded typed Codex refusal path:

• Invokes Codex through the structured --json JSONL channel and preserves the producer-owned turn.failed.error.codex_error_info value losslessly.
• Carries codex_error_info through the Lua result and adoption records, including CODEX_EFFECT, effect.json, result.json, and completed status.json.
• Reuses completed adoption on an identical second call, returning the same typed value without spawning Codex again.
• Preserves existing successful-call Lua stdout behavior by exposing the final agent message rather than raw JSONL.
• Adds a real-process Unix integration test covering typed refusal transport, adoption replay, the untyped UNKNOWN control, and successful stdout projection.
• Repairs the regression control so typed and untyped failures use identical prose and exit status, isolating codex_error_info as the only variable.

中文摘要：本轮将 Codex 的结构化拒绝值从 JSONL 适配器贯穿 Lua 与 adoption 记录，并验证重复调用不会再次启动 Codex；测试控制样本已修正为仅改变 typed field。PR #374 已合并。
