docs: audit against v2.0.0; deployment guide (local ax and a separate Kubernetes cluster)

Every README and docs page checked against ousast --help, the code and the committed records. New docs/deployment.md (in the nav): what runs where today, this host's setup (up.sh, doctor, smoke Run, footprint), step-by-step guidance for a separate Kubernetes cluster with implemented vs planned stated per item (no cluster deployment has been made; kube context and doctor's registry check are hard-coded in doctor.py, egress.py, router.py), and what the plane/ manifests need changed. Decision-engine pages state slice 2 (six families, pooled and within-pair AUC, BLOCK offered nowhere, canary below 0.9 for three families, positives-only inflation) and that the engine is not adopted; exp-002 registered, not run, no result quoted. Fixed: model/judge.py reference (now model/pipeline.py), missing-key behaviour, .env reference (OPENROUTER_EMBEDDING_MODEL, store variables), docs extra, plane memory-normalise and ousast index listed, ax README's cluster table made precise. RELEASE_NOTES gets an Unreleased entry.
