Setup docs drift: 27 docker-compose services not mentioned in README

Hi — found a concrete contributor onboarding gap while comparing config files against docs:

docker-compose.yml defines 27 services (postgres, redis, clickhouse, minio, caddy + 22 more) — README.md has no mention of docker compose up

A new contributor follows the README, never starts the services, and hits connection failures immediately with no pointer to why.

Proposed fix — add to the Setup section in README.md:

# Start required services
docker compose up -d

Happy to open a PR if confirmed.
