Test / Create distribution (push) Successful in 19s
Test / Run NixOS test (push) Successful in 49s
Just returning an error after a successful call of commit will leave garbage behind with no way for the caller to clean them. This change ensures revert is always called after successful commit with at least per-process state enabled.

This is yet another implementation detail from before system.I, getting rid of this vastly cuts down on redundant seal state.

cat 124743ffd3 app: expose single run method
Tests / Go tests (push) Successful in 1m1s
Nix / NixOS tests (push) Successful in 3m20s
App is no longer just a simple [exec.Cmd] wrapper, so exposing these steps separately no longer makes sense and actually hinders proper error handling, cleanup and cancellation. This change removes the five-second wait when the shim dies before receiving the payload, and provides caller the ability to gracefully stop execution of the confined process.
