Build failure on Windows CI: `'uint32_t'` not declared in `ImNodeFlow.h` (missing `<cstdint>` include)

[NewYaroslav]

When building on Windows CI the compilation fails because ImNodeFlow.h uses uint32_t without explicitly including <cstdint>. Some toolchains happen to pull it transitively, but others (e.g., on GitHub Actions Windows runners) do not.

Environment

• OS: Windows (GitHub Actions runner)
• Build system: CMake
• C++ standard: C++17
• Compiler(s): MSVC / MinGW-w64 (both can hit this depending on transitive includes)

Proposed fix
Add an explicit include in ImNodeFlow.h near the other includes:

#include <cstdint> // for std::uint32_t / uint32_t

Yes , this is something that changed relatively recently, I'll have to add the include
