Adds dev/docker-compose.yml + dev/keycloak/realm-export.json + dev/README.md and Makefile targets so a developer can: make dev-up and get Keycloak 26 on :8080 with the breakpilot-dev realm pre-imported, plus pg-app (:5432), Redis (:6379), Mongo (:27017), and MinIO (:9000 + :9001). Seed users: test@breakpilot.dev / test — IT_ADMIN of tenant 'acme' admin@breakpilot.dev / admin — BREAKPILOT_ADMIN (platform staff) Realm includes a dev-portal public PKCE client (redirect URIs cover http://localhost:3000/* and http://*.localhost:3000/* so subdomain routing works in dev) and a dev-tenant-registry bearer-only client. Protocol mappers project tenant_id, tenant_slug, org_roles, products, plan, and tenant_status into every issued JWT — the contract portal + tenant-registry expect in prod, fronted by Keycloak attributes today. dev/ lives in orca-platform because this repo already documents the production topology that this compose mirrors. INFRASTRUCTURE.md §1 sets dev as 'docker-compose on developer laptops' — this is that compose. Refs: M0.1+ (precondition for local-dev work on tenant-registry / portal)
