fix(hardware): SM count 50→16 confirmed on Phanthy Cloud BI-V100

ixsmi + torch.cuda.get_device_properties confirmed:
- multi_processor_count: 16 (not 50 as in spec sheet)
- compute_capability: 7.0 (Volta-compatible)
- max_threads_per_SM: 8192
- total_memory: 32GB per GPU
- SM clock: 1500MHz (max 2500MHz)

Impact: bandwidth_per_sm = 900/16 = 56.25 GB/s (was 18 GB/s at 50 SM)
All occupancy and tile-size calculations need revision.
