NavGrid Apply Tile Costs

Applies per-tile traversal costs to a NavGrid from a tilemap using explicit tile mappings.

Parameter	Description
NavGrid	NavGrid to modify.
Tilemap	Tilemap to read tiles from.
Mappings	Tile-to-cost mappings to apply.
Apply Default For Unmapped	If true, uses Default Cost for tiles not in mappings.
Default Cost	Cost used for unmapped tiles when default is enabled.
Only Walkable	If true, only writes cost on walkable cells.
Write Mode	How to combine with existing cost (Set, Add, Max, Min).

Example

1. Map MudTile to higher cost and RoadTile to lower cost.
2. Set Write Mode to Max so costs only increase where needed.
3. Run before pathfinding so A* can prefer cheaper routes.
