Fix crash in detectPlatform: handle negative e_lfanew offset
For pure DOS executables, the e_lfanew field at MZ header offset 0x3C
is uninitialized garbage. Duke Nukem 2's EXE had bytes that form a
negative int32 (-1878619136), which was used as an array index causing
ArrayIndexOutOfBoundsException.

Now checks peOffset < 0 and returns 'dos' (no Windows signature found).

Dostalgia — Quarkus Edition

A nostalgic DOS game hub. Upload your old DOS games, scrape artwork, and play them directly in the browser via js-dos (WebAssembly DOSBox).
