Build fails on Fedora Linux 42

[Ash-Olorenshaw]

Describe the bug On Fedora Linux 42, using G++ 15.2.1 20250808 (Red Hat 15.2.1-1), when running mvn install, build fails with:

Exception.h:35:38: error: ‘uint16_t’ does not name a type   

To Reproduce Steps to reproduce the behavior:

1. Clone repo
2. cd stylus && mvn install
3. See error:

Screenshots

Desktop (please complete the following information):

• OS: Fedora Linux 42
• Maven: Apache Maven 3.9.9 (Red Hat 3.9.9-14)
• G++: 15.2.1 20250808 (Red Hat 15.2.1-1)

Additional context To fix, I just chucked #include <cstdint> into stylus-jni/src/main/cpp/dependencies/jni-voithos/include/Exception.h and then installed libstdc++-static and build ran perfectly. If you like, I can put in a pull request for this.
