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.
