The image name was packed into the value, so the flag needed a hand-rolled
KEY=FROM:TO parser with its own malformed-input branch, and 'window' named the
wrong thing — the tool has two kinds of window (version ranges and, on the date
fallback, real date windows) and the flag meant only the first.
Now each part is its own argument: --image redis 7.4 8.10, repeatable, all in
one call. argparse enforces the arity, so the string parsing and its error path
are deleted. 'windows' survives internally as the computed-range concept.
Counts unchanged: discourse 128 with redis / 123 without, gitea 2.
