audit: phase 0 tooling for file-by-file 40250 porting

- refroot.py: one reference-root resolver (MT_40250_SOURCE, then manifest)
  used by every audit script; missing tree or fingerprint input is an error
- port_map.py: per-function inventory of active 40250 units plus the
  40250 Python root, status/queue/init/show/check, 40250: tag scan
- manifest: fix 18 wrong reference paths (Python UI now points at the
  40250 Client/Eternexus/root, not the m2dev assets/root), drop 2 deleted
  implementation files, move 64 prose test entries to evidence.commands
- first port-map entry: PythonPlayerEventHandler.cpp
- roadmap replaced by a batch/unit queue
