Enable strict concurrency checking in CI (#11)

Enable strict concurrency checking in CI

### Motivation

To further avoid concurrency bugs, enable complete concurrency checking in CI.

### Modifications

Added the compiler flag to the docker-compose scripts.

### Result

If a warning of this nature comes up, because we have warnings-as-errors, it'll fail CI.

### Test Plan

Locally built without any warnings with the flag enabled.
