v1.41.0

Timer: type the countdown's layout; quicker Fill with AI (v1.41.0)

Three checkboxes (Show milliseconds, Full-size milliseconds, Fixed
00:00:00) described one thing, the shape of the numbers. The countdown
now has a FORMAT box under Advanced instead: M:SS.000 turns a 20-second
timer into 0:20.000, HH:MM:SS gives 00:05:00, and the first unit
stretches on its own. Empty is the usual layout, and it renders
byte-identically to v1.40.0.

Fill with AI was slow on the free model pool. It now defaults to
OpenRouter's auto router on its lowest cost tier, about a fraction of a
cent per fill. A key with no credit falls back to the free models on its
own, so nobody loses the feature. That path is tested against a faked
OpenRouter only; no live call has been made from the dev machine.
