- Introduced a new `CoarseToFineWaterPath` module to enhance pathfinding efficiency for boats by utilizing a coarse map to guide fine path searches.
- Implemented a two-stage pathfinding approach: a coarse search on a low-resolution map followed by a refined search on the full-resolution map.
- Updated `TransportShipExecution` and `TransportShipUtils` to leverage the new coarse-to-fine pathfinding method, improving routing decisions and handling of retreat paths.
- Added tests to validate the new pathfinding functionality and ensure robustness in various scenarios.
