"""Deep string analysis of cq.exe (launcher shell) to find how it spawns cq2.exe.

cq.exe (1.6MB) reads env.json (gameid/token) and spawns cq2.exe.
Hunt for:
  - CreateProcess command templates (e.g. "cq2.exe %s")
  - Quote/percent format strings near 'cq2' or 'exe'
  - Full command lines in adjacent data
