makalin/CornerFix

CornerFix — Injected macOS window sharpener: libcornerfix.dylib + cornerfixctl reshape standard titled windows (corner radius 0–24). Live enable/reload via Darwin notify, per-bundle plist overrides, presets, cornerfix-inject, and unsigned CornerFixTestApp. Swizzles private AppKit window APIs; tweak/loader workflow—not App Store/hardened-app safe.
