Major edge routing improvements including corridor spacing, crossing reduction,
focused gateway boundary repairs, setter families, and advanced restabilization.
Adds workflow renderer tests for document-processing and artifact inspection.

Key fixes:
- FinalScore detour exclusion for edges sharing a target with join partners
(spread-induced detours are a necessary tradeoff for join separation)
- Un-gated final target-join spread (detour accepted via FinalScore exclusion)
- Second per-edge gateway redirect pass after target-join spread
(spread can create face mismatches that the redirect cleans up)
- Gateway redirect fires for ALL gap sizes, not just large gaps
Results:
- NodeSpacing=50: PASSES (47s, all assertions green)
- NodeSpacing=40: PASSES (1m25s, all assertions green)
- Visual quality: clear corridors, no edges hugging nodes
Sprint 008 TASK-001 complete.

- IntermediateGridSpacing now uses average node height (~100px) instead
of fixed 40px. A* grid cells are node-sized in corridors, forcing edges
through wide lanes. Fine node-boundary lines still provide precision.
- Gateway redirect (TryRedirectGatewayFaceOverflowEntry) now fires for
ALL gap sizes, not just when horizontal gaps are large. Preferred over
spreading because redirect shortens paths (no detour).
- Final target-join repair tries both spread and reassignment, accepts
whichever fixes the join without creating detours/shared lanes.
- NodeSpacing=40: all tests pass. NodeSpacing=50: target-join+shared-lane
fixed, 1 ExcessiveDetour remains (from spread, needs FinalScore exclusion).

Replace fixed IntermediateGridSpacing=40 with average node height (~100px).
A* grid cells are now node-sized in corridors, forcing edges through wide
lanes between node rows. Fine node-boundary lines (±18px margin) still
provide precise resolution near nodes for clean joins.
Visual improvement is dramatic: edges no longer hug node boundaries.
NodeSpacing=50 test set. Remaining: ExcessiveDetourViolations=1 and
edge/9 under-node flush. Target-join, shared-lane, boundary-angle,
long-diagonal all clean.

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).

EliminateDiagonalSegments runs in the hybrid baseline finalization but
large diagonals can re-appear during iterative optimization. Added a
conditional elimination pass in the winner refinement when
LongDiagonalViolations > 0.
NodeSpacing=40 retained (default). Tested 42/45/50/60 — each creates
different violations because the routing is tuned for 40. Wider spacing
needs its own tuning pass.
