Gundam Breaker 4 UltraWide Fix v1.0.0

32:9 / 21:9 ultrawide support for Gundam Breaker 4 (UE4.27) via SUWSF +
Ultimate ASI Loader. Forces Hor+ FOV (AspectRatioAxisConstraint=MaintainYFOV)
and disables pillarboxing, patched in decrypted memory at runtime so it holds
through missions (the exe is SteamStub-encrypted; a static patch is impossible).

Confirmed working in gameplay at 5120x1440 (Samsung Odyssey G93SC) on Proton.
Requires WINEDLLOVERRIDES="dsound=n,b" on Proton so the loader injects.

Includes: patch/SUWSF.ini, Proton installer with clean uninstall, release-zip
builder, and runtime dump/verify tooling. Third-party bundles under MIT (see
THIRD_PARTY.md).
