Description

dune fmt and dune build @fmt should only format the code - not build it. They behave as expected when no lockdir is present, but the presence of a lockdir causes the project's dependencies to be built before any formatting takes place.

Research direction

Reproduce dune fmt and dune build @fmt in a project with a lockdir, then compare their behavior without one. Trace the formatting entry point and lockdir dependency handling; done means both commands format the code without building project dependencies.
