Fix for Issue #78: Remove extra trace lines in post-processing step

Problem

When multiple MSP pairs in the same net share a pin, they get routed independently and produce overlapping segments near the shared pin. Additionally, when a route is spliced into an existing path, consecutive duplicate points can appear, rendering as spurious extra trace lines.

Solution

1. removeDuplicateConsecutivePoints - Removes consecutive duplicate points from trace paths. When a route is spliced, the concatenation can produce consecutive duplicate points (same x,y) which render as spurious extra trace lines.

2. removeNetSegmentDuplicates - Removes duplicate trace segments within the same net. When multiple traces in the same net share pins, trims duplicate segments from the start and end of later traces while preserving path connectivity.

Files Changed

• lib/solvers/TraceCleanupSolver/simplifyPath.ts - Added removeDuplicateConsecutivePoints
• lib/solvers/TraceCleanupSolver/sub-solver/UntangleTraceSubsolver.ts - Apply deduplication when splicing routes
• lib/solvers/TraceCleanupSolver/removeNetSegmentDuplicates.ts - New file for cross-trace deduplication
• lib/solvers/TraceCleanupSolver/TraceCleanupSolver.ts - Apply removeNetSegmentDuplicates at output
