Silta 0.919

No longer needs the Visual C++ Redistributable (static runtime)
Fixed: hotkeys now work even with all features disabled
Added: use_polling input fallback for systems where key messages don't reach the overlay
Camera after save-load/alt-tab: no crash, no garbage, clears on device reset, with a clear "reload the save" toast
Photo-after-save crash eliminated; not-ready (1×1) shots skipped cleanly
[experimental] section for the shelved render toggles
