micheleandClaude Sonnet 5 fce8ff2d66 exp: fork real board top (fpga_neural_v2_top_openrow.v) with open-row SDRAM backend, verified functionally identical

SPI+board-level smoke test: 11/11 PASS, matching the unmodified
production top exactly. 8-seed nextpnr-ecp5 P&R sweep (N=4, real
v2_board_top.lpf pins, 64MHz target): 8/8 PASS on both, open-row
variant has BETTER margin than baseline (worst 83.34 vs 76.80 MHz,
mean 90.40 vs 82.53 MHz) -- not just no regression, a real improvement.
Not yet promoted over the production fpga_neural_v2_top.v (that swap
is still pending an explicit go-ahead); this commit only adds the
verified fork + its own smoke test, additive only.
