Add full V2 architecture: identity, content, studio (.NET 10) and file, render, notification, gateway (Go) services with vendored deps, plus DB migrations, event/API contracts, and an init-db script. Wire the Next.js frontend to the gateway: server-side JWT auth routes (login/register/refresh/logout/me), gateway fetch helper, and session/ cookie/jwt helpers under src/lib. Containerize the stack via docker-compose.v2.yml and per-service Dockerfiles. Base images resolve through a Nexus mirror (Docker Hub) and MCR directly; npm/NuGet pull from Nexus groups. Self-host fonts via next/font/local to avoid Google Fonts (geo-blocked). Add CI workflow and ignore .env.v2, *.stackdump, and .NET bin/obj. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
