docs: remove V100 from GPU bakeoff

V100 data was degraded by SDXL co-residence on CT 167 (31/32 GB VRAM
occupied, Gemma 4 models forced 95% onto CPU). Rather than ship a
prominent caveat, drop the V100 column entirely so the doc reports
only apples-to-apples measurements. V100 can be added back once an
isolated run is possible.

Removed: V100 column from TL;DR and per-model tables, hardware row,
caveat section, and associated raw JSONs under runs/pve197/. Harness
config keeps pve197 in HOSTS for future re-runs.

## V100 caveat — why the numbers are degraded
Mid-bakeoff I probed `GET /api/ps` on pve197 while the V100's Q8 MoE was
loaded:
```
gemma4:26b-a4b-it-q8_0 size: 30.5 GB size_vram: 1.57 GB
```
**Only 1.57 GB of the 30.5 GB model is actually resident on the V100;**
the other 28.9 GB is running on CPU via Ollama's CPU-offload fallback.
`nvidia-smi` corroborated: 31,754 / 32,768 MiB used, 0 % utilization
at probe time. That remaining ~29 GB of VRAM isn't free — it's held by
the SDXL pipeline on CT 167 (claude-avatar + ai-visualizer).
Impact on every V100 number in this doc:
- `gemma4:26b` Q4_K_M is 18 GB — doesn't fit in the ~1 GB of headroom
SDXL leaves, so it runs largely on CPU. Observed 8.3 tok/s is
consistent with CPU inference of a MoE 26B Q4 model.
- `gemma4:31b` Q4_K_M is 19.9 GB — same fate. Observed 1.55 tok/s is
consistent with dense 31B on CPU (dense kills you on CPU; only
~4 B params activate on the MoE, so the MoE suffers less).
- The Q8 variant (28 GB) never had a chance on the V100 while SDXL is
loaded. Bakeoff did not attempt it.
**To get isolated V100 numbers**, stop SDXL on CT 167 (or stop CT 167
entirely) and re-run `scripts/gpu-bakeoff/harness.py --host pve197`.
Left as a follow-up — whether that's worth the ai-visualizer
interruption is a judgment call. See "Open questions" below.

MoE variant Seth pulled on pve197 — worth measuring once isolated.
Q8 vs Q4 quality/speed tradeoff for the same model would be useful.
3. **Strix max-model fit.** Strix can probably host models that
wouldn't fit the discrete cards. A follow-up would pull a larger
model (70 B+ quantized) on matt-strix and see the Strix-only
performance ceiling.
4. **Contention behavior.** The V100 finding generalizes — whenever
the homelab is running coresident AI workloads, Gemma 4 inference
falls off a cliff. A "contention-aware routing" decision (don't
send latency-sensitive Ollama traffic to a card with SDXL running)
may be worth building into the mort-bot / openwebui gateway.
