handoff.py classifies completed downloads (console rom vs RPG-Maker fangame vs
patch, via bsdtar archive peek incl. RAR5), copies console roms into
Emulation/roms/<platform> for RomM, moves the full folder (rom + guides) into
the library archive, and renders note.md + handoff.json per hack for the
Obsidian publish step. Wired into the cycle; single /data mount keeps moves as
fast renames. Validated on 4 real games.
