fix: revert to Version 1 approach (tiles connected) + just add Y negate

Browse source 
Version 1 (X mirror, Y direct) had correct tile connections but N/S
flipped. Previous attempts to fix N/S also changed rotation handling
which broke tiles. This commit reverts tile processing (no flip),
reverts rotation (exact UB values), and only adds Y negation to
Version 1's working coordinates. No other changes.
