添加了MinerU的支持，对中文的财报适配更加优秀 |
层4 Python API (magic_pdf.tools.common.do_parse):
- try/except Exception 包裹，模型下载异常不穿透
- tempfile 临时文件 + try/finally 清理
层3 CLI (magic-pdf subprocess):
- 修复 shutil.which("mineru") → "magic-pdf"
- subprocess.run shell=False，timeout=300
- try/except Exception 包裹
代码重构:
- 抽取 _flatten_content_list + _build_document_from_blocks 消除 4 处重复
- 抽取 _cleanup_temp_files 统一层3/层4 清理逻辑
- 提取 4 个命名常量消除魔法数字
测试:
- 层3 CLI: 9 个 mock 测试 + 1 个 skip-if-not-installed 烟雾测试
- 层4 Python API: 8 个 mock 测试 + 1 个 skip-if-not-installed 烟雾测试
- MineruProcessor: 31 个单元测试覆盖全部 7 个接口
- 总计: 66 passed, 0 failed, pyright 0 errors

概述
MinerU 云 API v4 集成到 dayu-agent，作为 PDF 解析后端。当 Docling 解析失败（港股复杂 PDF 超时/崩溃）时，自动 fallback 到 MinerU 云 API。
核心收益：快手 2025 年报（374 页 / 9.9MB 港股 PDF）解析耗时从 Docling CPU >10min（未完成）降低到 MinerU 云 API 78.7s。
新增文件（5 个模块 + 2 个测试 + 1 个文档）
