Add configuration to vary floor sizes: FloorSizeMode enum, varyFloorSize, floorSizeMode and manualFloorSizes in MazeReworkConfig. MazeReworkGenerator now accepts explicit width/depth via an overload, threads width/depth through generation, and adds optional endBounds to placement logic; dead-end/furthest searches respect bounds. MazeReworkManager computes per-floor seeds and dynamic sizes (manual or randomized), instantiates per-floor generators, and passes end bounds between floors for both animated and instantaneous generation. Also includes minor IDE workspace.xml metadata formatting changes.
