docs: fix NIH-audit review findings (Codex round 1)

- Drop the AGENTS.md budget bump: trim filler words in the layout map
  and command comments so the new convention line fits the existing
  1680 ceiling (1679/1680; master was 1680/1680)
- timers/promises note: 'Replace both' -> all three sites, and add
  pty-local to the acceptance criteria (EN+ZH)
- execa note: 17 value-taking options plus boolean flags, not 18 (EN+ZH)
- rejected roll-up: lsp-local src is ~1,800 lines, not 2,112 (EN+ZH)
- re-record the three touched i18n pairs

 Two related test-infra hand-rolls compound the case:
 
-- `packages/support/llm-mock-server/src/cli.ts` hand-tokenizes 18 `--flag value` options (~45–60 lines of loop and value-extraction helpers) where the `node:util` `parseArgs` builtin is already the repo idiom (`cli-demo`, `acp-demo`, `verify-runtime-closure.ts`, `packages/sdk/scripts`).

 - `apps/web/tests/smoke-real.e2e.ts` and `apps/web/tests/scaffold.ts` carry two verbatim copies of a regex `.env` parser (~20 lines) where the `process.loadEnvFile` builtin has exactly the required no-override semantics — and the vitest e2e/snapshot/web configs already load root `.env` with it before these files run, making the copies arguably dead.
 - The snapshot harness hand-rolls three poll-until-deadline loops (`waitForPersistedTurnStart`/`waitForPersistedTurnEnd`/`waitForWorkspaceFile` in `packages/support/acp-snapshot/src/harness.ts`, ~55 lines) plus `waitForFile` in `crash-recovery.e2e.ts`, where `vi.waitFor`/`expect.poll` cover the shape — vitest is already a runtime dependency of `dsh-acp-snapshot`, so this adds nothing.

 另有两处相关的测试基础设施手写代码进一步强化了替换的理由：
 
-- `packages/support/llm-mock-server/src/cli.ts` 手工逐个切分 18 个 `--flag value` 选项（约 45–60 行的循环与取值辅助函数），而 `node:util` 内置的 `parseArgs` 早已是本仓库的惯用写法（`cli-demo`、`acp-demo`、`verify-runtime-closure.ts`、`packages/sdk/scripts`）。
+- `packages/support/llm-mock-server/src/cli.ts` 手工逐个切分 17 个带值的 `--flag value` 选项外加若干布尔标志（约 45–60 行的循环与取值辅助函数），而 `node:util` 内置的 `parseArgs` 早已是本仓库的惯用写法（`cli-demo`、`acp-demo`、`verify-runtime-closure.ts`、`packages/sdk/scripts`）。
 - `apps/web/tests/smoke-real.e2e.ts` 与 `apps/web/tests/scaffold.ts` 携带两份逐字相同的正则 `.env` 解析器拷贝（约 20 行），而内置的 `process.loadEnvFile` 恰好具备所需的「不覆盖已有值」语义；并且 vitest 的 e2e/snapshot/web 配置在这些文件运行之前就已用它加载了根 `.env`，这两份拷贝几乎可以视为死代码。
 - 快照 harness 手写了三个「轮询直到截止时间」的循环（`packages/support/acp-snapshot/src/harness.ts` 中的 `waitForPersistedTurnStart`/`waitForPersistedTurnEnd`/`waitForWorkspaceFile`，约 55 行），外加 `crash-recovery.e2e.ts` 中的 `waitForFile`，而 `vi.waitFor`/`expect.poll` 正好覆盖这种形态；vitest 本来就是 `dsh-acp-snapshot` 的运行时依赖，因此这不新增任何东西。
