Add EasyEDA Pro EPRO2 source ingestion (3/5 batch test)

打通 oshwhub origin=pro 现代 Pro 3.x 工程的 EPRO2 源抓取链路。3/5 modern Pro 项目完整解出（共 8423 docs / 542 MB plain）： - X86 主板 7374 docs / 481 MB plain (chain=85, editor=3.2.15) - 220V 桌面电源 771 docs / 26 MB plain (chain=28, editor=3.2.69) - ESP-VoCat 278 docs / 7.5 MB plain (chain=12, editor=3.2.91) 剩余 2/5 是 legacy Pro 2.x（立创泰山派 RK3566、梁山派），项目 meta 返回 branch_uuid=null + editorVersion="2.1.40"，没有 git-style chain 模型，文档直接挂在 boards[].sch/pcb 字段上，访问端点暂未挖通；元数据落库 metadata.json，source/ 留空。实现要点： - fetch_pro_source(): 4 步流程（project → branch HEAD → structures → /branches/<B>/histories/<HEAD> 即返完整 chain，无需 ?limit 批量端点）+ 逐 history 走 AES-128-GCM 解密（16 字节 IV，pycryptodome 原生支持）+ gunzip + 按 DOCHEAD 切 per-doc EPRO2 流 - EPRO2 解析坑：行末单 `|` 是行终止符不是字段分隔符，必须先 rstrip("|") 再 split("||")，否则 payload JSON 解析失败 silently swallow 导致 cur_doc 不设 → 第一轮 X86 板 7374 docs 抽出来只剩 2 个 - docType 实测远不止 BOARD/PCB/SCH/SCH_PAGE，还含 SYMBOL / FOOTPRINT / DEVICE / BLOB / FONT / CONFIG —— Pro 把组件库快照也随项目存到 history，下游做 EPRO2→KiCad 转换时必须先把这些 lib doc 加载进 symbol cache - Pro 2.x vs 3.x 是不同存储模型 —— 3.x 走 branch 模型（已打通）， 2.x 走 boards[] 直链（未打通）；判别条件：project meta 的 branch_uuid 是否为 null CLI 新增 --with-pro-source / --backfill-pro-source / --pro-cookie / --origin（按 origin 字段服务端过滤 listing API），crawl_one() 按 origin=pro 自动 dispatch 到 Pro fetcher。 schema：docType 类型从 integer 放宽到 [integer, string, null] （兼容 Std 的 1/3 + Pro 的 BOARD/SCH 等），新增 message_count 字段。 License 注意：本批 5 个项目全是 NC-SA / GPL，未达 Pro source doc §4.2 Forge 白名单（MIT/BSD/Apache/CC0/CC-BY/CERN-OHL-P/Unlicense）。按 CLAUDE.md "研究用、不再分发" 原则 raw 入库无碍；Forge 投影时另过白名单。详细技术细节见 docs/sources/easyeda_pro_source.md rev 3 + log.md。 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
