thejayman77 96d23ea8ee Ch441 TB review fixes: complete stall check + full&&d_wready coverage [READY FOR REVIEW]
Per Codex review of dd7ca4f (testbench only, RTL unchanged):
1. Stall check now requires d_wvalid to REMAIN asserted (catches a deassert) and
   compares the COMPLETE {d_wdata,d_wstrb,d_wlast} against the held beat, not just
   d_wdata.
2. Added saw_full_and_ready coverage flag (set on dut.full && d_wready) and a final
   check that FAILS if the distinguishing no-bypass case was never observed.

No RTL change, no simulations, no Quartus.
