fix: findings from the Cowork test, released as v0.1.1

The operator tested v0.1.0 in Cowork on 2026-11-11. README now says what
was measured there and what was not.

- miljo: no longer claims that kontroll compares "with tolerance, not bit
  for bit" when numpy or scipy differ from the note's versions. kontroll
  always compares byte for byte first, and numpy 2.5.3 gave bit for bit.
- kontroll --alt: show every differing line. The cut-off line now names
  the option instead of only counting the lines left out.
- skill simuler: the question before a run must be answerable with yes or
  no. In the test it became a choice between variants and the run stalled.
- skill forbedre: offer the working copy as a zip when the user cannot
  open the folder it was made in, as in Cowork.

263 tests pass; full kontroll: bit for bit with the note.
