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 removes the requirement to call fmsg.Exit on every exit path, and enables direct use of the "log" package. However, fmsg.BeforeExit is still encouraged when possible to catch exit on suspended output.

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.

This removes the dependency on external user switchers like sudo/machinectl and decouples fortify user ids from the passwd database.

This implements lazy loading of the systemd marker (they are not accessed in init and shim) and ensures consistent behaviour when running with a stub.

This change moves all user switcher and shim management to the shim package and withholds output while shim is alive. This also eliminated all exit scenarios where revert is skipped.

This change helps tests stub out and simulate OS behaviour during the sealing process. This also removes dependency on XDG_RUNTIME_DIR as the internal.System implementation provided to App provides a compat directory inside the tmpdir-based share when XDG_RUNTIME_DIR is unavailable.

The behaviour of print functions from package fmt is not thread safe. Functions provided by fmsg wrap around Logger methods. This makes prefix much cleaner and makes it easy to deal with future changes to logging.
