Per issue #153: `docker compose up -d` (docker-compose.yml) did not start
Temporal because it lived only in docker-compose.infra.yml. Users had to know
to run `setup.sh` which explicitly uses `-f docker-compose.infra.yml`.
Adding `include: - docker-compose.infra.yml` makes the full infra stack
(starting with Temporal) start with the default `docker compose up` command.
Both compose files define postgres/redis — the main file's definitions take
precedence via compose merge semantics, so no service conflicts.
