fix: fuzzy char-name OCR match; single-instance guard in detached launcher

- OCR reads FISTMAN as "fabiman" — SequenceMatcher >= 0.6 on the first
  word of the row handles the mangling
- start_bot_detached.bat kills existing main.py instances first: F11/F12
  are global hotkeys, so duplicate bots receive every press and fight
  each other (one starts while the other pauses/exits)
