chore(assets): deduplicate same-product images across doc trees

同一产品的素材散在多个文档树里各存一份（hardware/assets、
hardware/{zh,en}/<产品>、soft/<产品> 等），260 组、399 个副本，49MB。

判别「同产品」用两个条件，缺一不可：
  1. 文件名完全相同 —— 文件名不同说明是两个产品碰巧用了同一张图
     （cleam.png 与 clean_core_board.png），不是刻意复制
  2. 路径里不含同一产品族的两个不同型号

第 2 条拦下了 100 组：lpi3a/lpi4a、lpi3h/lpi4a、tang-nano/-1k/-4k、
tang-primer-20k/25k、tang-mega-138k/60k、spmod_eink/spmod_rfid。
这些合并会制造耦合——更新一个产品的图会让另一个产品的文档悄悄跟着变。

规范副本优先级：hardware/assets 共享区 > zh > 路径较短者。
引用改写基于解析后的目标文件，128 个 md 共 381 处，增删一一对应。

验证：断链 5 -> 5（新增 0），构建通过，抽查页面图片全部可取到。
