1e06ba6582 crawler: split sleep policy by host — chain blob fetches drop 5s -> 0.2s
The Pro modern fetch_pro_modern walks a per-history blob loop on
modules.lceda.cn (CDN-flavored host serving AES-encrypted EPRO2 streams).
We were sleeping 5s between every blob — same rate we use for the
rate-sensitive pro.lceda.cn API host. HAR analysis (proexportNew2.har)
shows the editor fires these blobs back-to-back without throttling, so
0.2s is plenty.

Walltime drops linearly with chain length:
  ESP-VoCat (chain=12):    80s sleep -> 22s sleep  (-72%)
  220V power (chain=28):  160s sleep -> 26s sleep  (-84%)
  X86 board  (chain~700, projection):  ~1h -> ~3min

Verified by re-fetching ESP-VoCat + 220V power: byte-identical output
across all per-doc .epro2 files (sha256 match), only fetched_at
timestamp differs in manifest.json. Two manifest files re-stamped as
proof of the validation runs.

API host sleeps (4x 5s in modern fetcher, 7x 5s in legacy fetcher) are
unchanged — those go to pro.lceda.cn /api/ which still wants polite
QPS<=0.2.

3282a028c4 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。
