Architecture fixes for open format data fidelity: - WOT now serializes full doodad/WMO placement arrays (positions, rotations, scale, flags, doodad sets) — was only storing counts, causing all placed objects to be lost on WOT round-trip - WOT loader parses placements back into ADTTerrain for client rendering - WOB Material struct added: preserves WMO material flags, shader type, and blend mode during WMO→WOB conversion (was geometry-only) - WOB doodad rotation: quaternion→euler conversion instead of hardcoded zero (placed doodads inside buildings now retain their orientation) - importOpen() deduplicated: delegates to pipeline::WoweeTerrainLoader instead of duplicating 100 lines of parsing code
