Add same-net trace alignment phase

[MinhThienNguyen040905]

/claim #29

Summary

• Add a dedicated SameNetTraceAlignmentSolver pipeline phase after trace cleanup.
• Align close overlapping same-net horizontal/vertical internal trace segments onto a shared axis.
• Preserve terminal segments so pin endpoints do not drift.
• Skip different-net candidates and reject alignments that would introduce a new different-net intersection.

Verification

• npm exec --yes --package bun -- bun test tests\solvers\SameNetTraceAlignmentSolver\SameNetTraceAlignmentSolver.test.ts
• npm exec --yes --package bun -- bun test tests\examples\example29.test.ts tests\examples\example34.test.ts
• npm exec --yes --package bun -- bun test
• node node_modules\typescript\bin\tsc --noEmit
• npm run build
