fix: New Phase To combine same-net trace segments that are close together

[JirA44]

Solution for #29

Approach: Feasibility: partial (AI needs reproduction context to validate proximity logic) Expected deliverable: Implementation plan + reproduction example for trace segments Winning approach: 1) Create reproducible trace segment test case 2) Implement new pipeline phase checking segment proximity for mer
