sim-setup status shows Postgres and Redis as absent when they're running in the Compose stack #8353

After a Quick setup with sim-setup 1.0.28 on macOS, npx sim-setup status prints:

postgres (sim-postgres):  absent
redis (sim-redis):     absent
app (:3000)       ✓
realtime (:3002)  ✓

Both are actually up and healthy. docker ps shows sim-<project>-db-1 and sim-<project>-redis-1, which is how Compose names them.

It looks like detectContainer in packages/sim-setup/src/detect.ts matches the exact names sim-postgres and sim-redis, which only exist for standalone containers. Looking up the Compose project's db and redis services instead (for example by the com.docker.compose.project and com.docker.compose.service labels) would fix it. As it is, a first-time user sees "absent" next to their database and assumes setup failed.

Related, smaller: running npx sim-setup stop from a different directory prints "No Sim install detected. Run npx sim-setup first." That reads like an instruction to install again, when the real fix is to run it from the parent of the sim/ folder.
