feat(nav): 17.3 - a map in square tiles (nav_tiled, nav_tile_build; a tile must be a whole number of cells or its seams never join, and the shim refuses one that is not; 64-bit polygon refs for 16384 tiles), ground as a NavGround with boulders as convex footprints, one save format for one tile or many, and nav_random_near - a reachable point from the caller's seed, bit-identical on the Mac and the PC. 10 tests on both
