Fix terrain loss after map transition and GPU crash on WMO-only maps

Browse source 
Three fixes:
1. Water captureSceneHistory gated on hasSurfaces() — the image layout
   transitions (PRESENT_SRC→TRANSFER_SRC→PRESENT_SRC) were running every
   frame even on WMO-only maps with no water, causing VK_ERROR_DEVICE_LOST.

2. Tile cache invalidation: softReset() now clears tileCache_ since cache
   keys are (x,y) without map name — prevents stale cross-map cache hits.

3. Copy terrain/mesh into TerrainTile instead of std::move — the moved-from
   PendingTile was cached with empty data, so subsequent map loads returned
   tiles with 0 valid chunks from cache.

Also adds diagnostic skip env vars (WOWEE_SKIP_TERRAIN, WOWEE_SKIP_SKY,
WOWEE_SKIP_PREPASSES) and a 0-chunk warning in loadTerrain.
