[Klaud Cold] Simplify agentic synthetic-AL checklist item: drop engine-specific knobs / 精简 agentic 合成 AL 清单条目：移除引擎特定参数

[functionstackx]

Summary

Follow-up to #2160: the checklist template item for agentic spec-decode synthetic acceptance now states just the rule — simulated synthetic acceptance with the AL value from the committed golden curve in golden_al_distribution/. The engine-specific mechanics (SGLANG_SIMULATE_ACC_* env vars, vLLM synthetic rejection sampling in --speculative-config) remain only in the verifier prompt's Check 10, which is where they are enforced.

中文说明

作为 #2160 的后续：清单模板条目现仅陈述规则 —— 启用模拟合成接受、AL 取值来自 golden_al_distribution/ 的已提交黄金曲线。引擎特定实现（SGLANG_SIMULATE_ACC_* 环境变量、vLLM --speculative-config 合成拒绝采样）仅保留在验证器提示词的 Check 10 中执行。

LGTM — docs-only wording simplification in the PR review checklist (EN + ZH); the substantive rule is unchanged and the enforcing verifier is untouched.

What was reviewed:

• Diff scope: two checklist markdown files only; no code, CI, or verifier changes.
• Confirmed both EN template and ZH template/mirror item (#6) are updated consistently, keeping the same rule (simulated synthetic acceptance + golden AL curve + free draft length choice).
• Confirmed the CI signoff trigger phrase ("As a PR reviewer and CODEOWNER, I have reviewed this and have") is preserved unchanged.

Extended reasoning...

Overview

The PR modifies only docs/PR_REVIEW_CHECKLIST.md and docs/PR_REVIEW_CHECKLIST_zh.md, replacing one long checklist bullet with a shorter version that states the rule (simulated synthetic acceptance with AL from the golden curve for that model / thinking mode / draft length) but drops engine-specific parameter names (SGLANG_SIMULATE_ACC_LEN, --speculative-config fields). The ZH file updates both the copy-paste English template block and the mirrored Chinese explanation for item #6 in lockstep.

Security risks

None. Pure documentation wording change with no executable content, links unchanged in target, no template trigger-phrase alteration.

Level of scrutiny

Low. This is a minor editorial follow-up to #2160 that shortens a checklist line while preserving semantics — the engine-specific mechanics still live in the verifier prompt's Check 10 where they are actually enforced. The CI signoff-verify trigger line ("As a PR reviewer and CODEOWNER, I have reviewed this and have") is preserved verbatim, so no risk to signoff-verify.

Other factors

Bug hunter reported no findings. Both language files are kept in sync, and the ZH file's item #6 gloss is updated to match the new English wording. Straightforward to shadow-approve.
