elksharp-svg: fix bridge gap detection for short segments near bends

Browse Source 
Reduce the corner radius used in EnumerateEffectiveSegments for bridge
gap detection from 40px to 12px. The 40px pull-back eliminated segments
shorter than 80px from crossing detection, causing 3 of 4 crossings
with edge/22's vertical to show no visual "cut" effect. With 12px
pull-back, crossings on segments as short as 25px are now detected.

Bridge gap count: increased from ~4 to 11 in the document processing
render — all visible crossings now show the cut/bridge effect.
