Aaron Kimbrell 1aeede3cd1 fix: address PR review feedback for raw terrain parsing
- Fix integer division bug in scene map lookups (was truncating to 0)
- Fix indentation throughout Raw.cpp, DEVGMCommands.cpp
- Add missing <algorithm> and <set> includes in dZoneManager.cpp
- Add missing width/height/scaleFactor guards in SpawnAllScenePoints
- Fix %llu -> %zu for size_t format specifiers
- Simplify no-op worldY calculation (y / scale * scale -> y)
- Remove redundant ternary guards in GetSceneIDFromPosition
- Fix misleading "Spawned LOT" feedback message
- Update info.settings to use LwoNameValue::Insert API (post-merge fix)
- Refactor SceneColor to static constexpr std::array (no heap alloc)
- Make NiColor constructors constexpr
- Remove duplicate CDZoneTableTable.h include
