Steve Markgraf 040bdb24a4 Optimize async FIFO critical path and add CLI build system
Replace chained adder in rptr_empty/wptr_full with parallel
pre-computation (rbin+1, rbin+2) and mux selection. This reduces
the critical path from ~9 to ~5-6 logic levels, improving clk_pixel
Fmax from 120.8 to 166.7 MHz (+38%).

Add build.sh/build.tcl for headless CLI builds via gw_sh with
timing-driven PnR and increased placement/routing effort.
