yxxandClaude Code c9c5f81d49 fix(export): 增加文档级组合复杂度预算与并发渲染限制
针对 PR 审阅 P1「组合复杂度仍可长时间占满导出线程」与 P3「EXPORT_OUTPUT_TOO_LARGE 误标 HTTP 413」:

- plot: FunctionPlot 记录整块 AST 节点数(node_count),parser 累计
- html: 单篇文档累计节点预算 _MAX_TOTAL_PLOT_NODES=8000,超限回退占位
- service: 并发渲染信号量 MAX_CONCURRENT_RENDERS=2,超限额任务排队等待
- docs: 错误码区分同步 HTTP 错误与异步任务错误,EXPORT_OUTPUT_TOO_LARGE 由
  error_code 返回而非 HTTP 413
- 补充节点预算与并发限制两条回归测试(全量 627 通过)
