Description
Current bridge density capped at 100% max prevents line overlap, causing micro-gaps every 5-6 lines despite perfect flow/speed.

Photos: [Upper=0.8 flow, Lower=0.75 flow with gaps][IMG_20260224_134908.jpg]

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Requested: Add "Bridge overlap" slider (100-150%) in Process > Quality > Bridges, like perimeter overlap.

Why crucial
✅ Mirror surface finish without gaps
✅ Pro-level bridges for Voron/Bambu users
✅ Reduces post-processing

Current vs Proposed

Current	Proposed
Bridge flow ratio	Bridge flow ratio
Bridge density ≤100%	Bridge overlap 100-150% ← NEW
Bridge speed	Bridge speed

Proof of concept
Voron Switchwire test arch:

0.75 flow + 0.15mm Z distance = smooth fusion
But micro-gaps every 5-6 lines (see photo)
+0.07mm thickness (near perfect)

Implementation hint
src/slicer/bridge.cpp: line_spacing *= (2.0 - overlap_ratio)

Describe alternatives you've considered
