feat(overlap): auto-recheck the active plate after layout edits settle

Browse Source 
Nest windows now rerun the overlap check once the layout has been
unchanged for 0.5 s, instead of leaving 'Overlaps: not checked'. Edits
show 'Overlaps: check pending...'; drags are caught by the paint-time
pose stamp, collection edits by their events. The check waits while a
mouse button, modal dialog or fill is active, supersedes a running check
when the layout moves again, and does not retry a canceled or failed
layout until it changes. Rechecks use the incremental analyzer, so only
the moved parts' neighbors are recomputed.

Automatic results update only the canvas label (the status bar keeps the
last command's message) and keep Display > Off. Check Active Plate still
runs immediately. InvalidateOverlapCheck now also drops cached material.
