useHotkeys pushed every keydown into the sequence buffer and only matched when the whole buffer equalled a shortcut. Two things broke that: the Shift keydown of "g" then "!" put "shift" in the buffer (so "g !", go to Spam, never matched), and any key pressed within 800 ms before a sequence (for example "j" and then "g i") left a stale entry in front of it.
Modifier keys no longer enter the buffer, and a sequence now matches when it ends the buffer. A single key still only matches as the whole buffer, so lone shortcuts behave as before. The matching moved to use-hotkeys-utils.ts with a small test.
