tools: durable BAR0 GR register sampler + analyzer (gr-regs/)
reg_sampler.py: high-rate read-only MMIO sampler for the physical GPU's
PGRAPH/FECS/SKED/PFIFO registers (FECS current-context valid + pointer,
SKED CWD table occupancy/activity, GRFIFO, FE QMD-virt, PMC_ENABLE) with
analyze_regs.py for value distributions and transition timelines. Recorded
ground truth and register semantics in tools/gr-regs/README.md. Used to
capture the live distro-driver CUDA reference (FECS VALID=1, CWD table
0x3f002000 while running) and to observe the ladder's forwarded launch
(CWD entry + SKED processing after the mode-35 lane enable).
