Master PDF Editor Patch

Bypasses license validation for Master PDF Editor 5.9.98 using inline hooking via tinyhook.

Supports both Apple Silicon (arm64) and Intel (x86_64) architectures.

How it works

The dylib hooks MainWindow::ValidateLicense to force license flags, then calls QDocTab::SetRegProgram to complete activation.

Build
