Phase 1 MVP: crawl 10 high-quality oshwhub projects into LFS

Why:
- Charles 指定：先爬 10 个高质量项目存 Gitea LFS，一个项目一个文件夹，
  保留原文件和 URL。先以小批量验证 schema + LFS 流水线，放量前再拍板
  存储规模。

What:
- crawlers/oshwhub: 列表 API (`/api/project?sort=hot`) + SSR HTML 解析，
  一次性产出 metadata / description / cover / files / _urls
- schemas/project.schema.json: 跨源统一 schema
- docs/sources/oshwhub.md: API 入口 / 字段映射 / 陷阱调研
- pyproject.toml: httpx[http2] 单依赖
- .gitattributes: data/raw/**/files/** 一律走 LFS（规则写窄，避免误伤 schemas/*.json 等）
- .gitignore: 移除 data/raw/* 排除（改走 LFS 入库）

10 个项目覆盖：调试器 / 加热台 / 盖革计数器 / 数控电源 / 焊台 /
智能手表 / USB 测电流 / ZVS 感应加热 / AI 开发板 / 红外热成像。
共 52 附件 ≈ 524 MB 入 LFS，筛选判据 grade=4 & likes>=100 & 多样性。

Known gaps（见 plan.md § Phase 1.4）：
- EasyEDA 源 JSON 需登录 (u.lceda.cn)，v0.1 跳过
- fs-web-stream.jlc.com 的工程源下载未测
- scripts/validate.py 自动 schema 校验未实现

+# 自制ST-LINK V2-1（开源版本）
+
+最近迷上了攻城狮工具的制作，因手头有个潘多拉开发板，板载一个STLINK/V2.1，这玩意支持STM32调试，还带了一个虚拟串口和虚拟U盘下载，所以用立创EDA打造了一个小巧的STLINK/V2.1
