ci(gadfly): new build sha-d0de034 + per-lens concurrency

Bump the gadfly image to sha-d0de034 (adds GADFLY_PROVIDER_LENS_CONCURRENCY)
and move ollama-cloud's concurrency from the MODEL axis to the LENS axis:
- GADFLY_PROVIDER_CONCURRENCY: ollama-cloud=1 (one model at a time)
- GADFLY_PROVIDER_LENS_CONCURRENCY: ollama-cloud=3 (its 3 lenses concurrent)

Net: still 3 models, but reviewed serially — the first model's consolidated
comment lands sooner and each model finishes faster, while the other two
models' comments arrive in series after it (instead of all 3 in parallel).
