Adds a short subsection under 后门 documenting the upstream author's
QQ-group claim that another contributor used a backdoor to remotely
read user files, with the chat screenshot as evidence.

Promote the standalone mapping/BACKDOOR.md into the main README so the
backdoor discussion (screen capture, RCE / file download / file browse
packets, the upstream author's contradictory responses) is visible
without an extra click. Includes captured Trace screenshots, the
ToString-leaked CPacketSystemInfo class and the author's QQ-chat /
Bilibili rebuttals.
File moves:
- mapping/BACKDOOR.md -> inlined into README
- mapping/screenshot-*.png -> img/ (alongside the other readme assets)
- Several new images under img/ (RCE, backdoor*, CPacketSystemInfo, meme)
