Fix target-join at NodeSpacing=50 via final post-pipeline spread

Browse Source 
Added final target-join detection and repair after per-edge gateway
fixes. The per-edge redirect can create new target-join convergences
that don't exist during the main optimization loop. The post-pipeline
spread fixes them without normalization (which would undo the spread).

NodeSpacing=50 progress: target-join FIXED, shared-lane FIXED.
Remaining at NodeSpacing=50: ExcessiveDetourViolations=1 (from
target-join spread creating longer path).

NodeSpacing=40: all tests pass (artifact 1/1, StraightExit 2/2,
HybridDeterministicMode 3/3).
