feat: draggable crossover handles with dynamic lo<=hi limit

Browse Source 
Replace the two plain crossover sliders with a horizontal log-frequency strip
(LOW/MID/HIGH) and two draggable handles, plus number boxes (double-click to
type). Handles and boxes enforce a dynamic limit so lo/mid never crosses
mid/hi, on top of each param's own range. Lives in the editor/ widget module.

Known limitation: the lo<=hi limit is editor-only, so host automation can write
the two params past each other (briefly inverting the mid band). The DSP clamps
to monotonic, but FL's automation can misbehave once inverted. Left as-is.
