Jason 254c0e6f03 Improve timing margins with targeted datapath register tuning 
Reduce routing pressure on CIC/NCO critical paths and move Doppler BRAM read-address registers to sync-reset datapath logic so Build 13 closes with stronger setup/hold slack while preserving functional behavior.

range_bin_decimator.v
Fix range_bin_decimator overflow guard priority bug: group completion now takes precedence over overflow guard in ST_PROCESS, ensuring all OUTPUT_BINS outputs are emitted when sufficient input samples exist. Split formal property 5 into 5a (upper bound) and 5b (exact count when start_bin=0), added Cover 4 for overflow guard path, reduced BMC depth to 50.
