Per-step execution loop

For every step, follow this exact order:

1. Announce the step.
2. Run the step and fix failures until it passes.
3. Give a very brief report of changes made in that step.
4. Continue to the next step.

Example announce line:

Doctor: Step 2/3 - mix check

Example report line:

Step 2 report: lib/surge/foo.ex - removed unused alias; wrapped side effect in after callback.
