biggy a50666355c feat(gui): add knob value popup, tooltips, tab cycling, and layout system 
Add a floating value label near the cursor while dragging a knob, giving
immediate feedback without altering slider behaviour. Inherit
SettableTooltipClient on ToggleButton so setTooltip works consistently
with knobs and combos.

Introduce a shared layout constants namespace in PluginEditor so every
panel, row and control position derives from one spacing system. Add
tooltips to all knobs, combos, toggles, and buttons. Add Tab/Shift+Tab
tab cycling via keyPressed, with a TooltipWindow for hover hints.
