Subject: [PATCH 01/18] feat: snap same-net parallel traces to the same
 coordinate

Closes #34

Adds a new `snapSameNetTraces` step to `TraceCleanupSolver` that detects
parallel segments belonging to the same net that are within a configurable
threshold (default 0.05) of each other and snaps them to their midpoint
coordinate, eliminating near-coincident same-net trace lines.

- New file: lib/solvers/TraceCleanupSolver/snapSameNetTraces.ts
- Modified: TraceCleanupSolver pipeline adds `snapping_same_net` step after `balancing_l_shapes`
- New file: tests/solvers/TraceCleanupSolver/snapSameNetTraces.test.ts (7 unit tests)
