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

+Replace all three with `import { setTimeout } from 'node:timers/promises'`:
 
 - llm-retry: `try { await setTimeout(delayMs, undefined, { signal }); /* retry */ } catch { /* abort → fail */ }` — with a signal, the promise rejects only with the abort error, and a pre-aborted signal rejects immediately; behavior is identical, including timer clearing on abort. The empty `catch` names the abort rejection per the repo's empty-catch rule.
 - workflow-workerthread: `setTimeout(ms, undefined, { ref: false })` — exact semantics including not holding the event loop open.

 - llm-retry：`try { await setTimeout(delayMs, undefined, { signal }); /* retry */ } catch { /* abort → fail */ }`。传入 signal 后，该 promise 只会以 abort 错误拒绝，已提前中止的 signal 则立即拒绝；行为完全一致，包括中止时清除定时器。按仓库的空 catch 规则，这个空 `catch` 注明其吞下的是 abort 拒绝。
