Subject: [PATCH 1/4] feat: line mode says details only with --verbose

By default a run prints what it installs, the BIOS folder, the progress
at a terminal, the result and the next step. The steps, the per-file log
lines, the counts and the reasons a file is left out come back with
--verbose. --check gives the count and the folder, and lists each file
with --verbose. The installer page shows the default run and walks
through the --verbose one.

Subject: [PATCH 2/4] feat: full screen keeps its notes on Details

The plan, Confirm and the result say what happens, its size, where and
the next step. Their counts, free space, backup and save notes, kinds,
reasons a file is left out, per-file failures and commands move to a
Details screen: d on the plan, Confirm and the result, the Details row
on the plan, Y, o or Tab on the result. Opened on the result, they are
also said in the terminal after Exit. Installing lists the files that
went well only with --verbose, and --verbose draws every line in place.
The log line reads Log: so that Details names one thing.

--check prints its count, the folder and the remedy in both modes, so
that --verbose prints every default line. Each golden screen gets a word
budget per size, and a test proves the screen and its Details together
equal the --verbose screen.

Subject: [PATCH 3/4] chore: give each journey a word budget

The full-screen journeys sum the words of every screen they stop on,
and one screen of them may show 90 at most. The same journeys in line
mode keep to their lines and words, print every default line again with
--verbose, and run to their end with no terminal and no --yes. A path
is no word: its length is the machine's.

Subject: [PATCH 4/4] fix: say what to act on by default

Five lines the default text hid are back where the user reads them:
- the result names each failed file again, after Exit too;
- a run, --check, the plan and the result count the files an emulator
  needs that are not available here, --verbose or Details naming them;
- --check names each copy that fails its check, the files that sit too
  deep and what a run copies, and says such a copy is backed up; only
  the plain missing files wait on --verbose;
- the plan and the result keep the count of save files left out and the
  remedy, the reason going to Details;
- the plan counts the --from files that could not be read where no row
  names them, and says another drive to add.

Exit codes are unchanged. The result's word budget rises by the failed
file line.
