- Extend undo/redo to snapshot alpha maps and texture layers alongside heights — texture painting operations are now fully undoable - Bracket paint mode with beginStroke/endStroke like sculpt mode - Fix stale static char buffer in quest objective loop (showed wrong objective's description when editing multiple objectives) - Zero-initialize all quest UI text buffers for null termination safety - Fix unused variable warnings in terrain_editor.cpp
