2025-03-27 release

- Got rid of C-runtime, it's 100% SDL3 now
- no more nested functions
- No more surface rendering. You can't mix rendering APIs in SDL3 anymore. This required a major refactor.
- Since I was refactoring, went ahead and added support for multi-image viewing with SDL3's drag & drop events.
