fix: merge same-net collinear traces (#34)

[a25955813-cloud]

Fixes #34

What this does

Merges collinear trace segments that belong to the same net and share the same X or Y coordinate into a single segment.

Changes

• Added lib/utils/mergeCollinearTraces.ts — core merge algorithm
• Added lib/solvers/SameNetTraceMergeSolver.ts — solver class
• Added tests/merge-collinear-traces.test.ts — 8 passing tests

How it works

1. Groups segments by net ID
2. Separates horizontal/vertical/diagonal segments
3. Merges overlapping or touching segments on the same axis
4. Leaves diagonal segments untouched

Hi @tscircuit, I've successfully linked my bank account on Algora and it's showing as Active. Could you please confirm if the reward process has been initiated? Thanks!

I have updated this PR with a more robust geometric approach. I've added a specialized merge-logic.ts within the TraceCleanupSolver directory that uses a distance tolerance to unify traces. It handles floating-point errors and unifies overlapping segments, providing a more complete fix for #34 than simple state resets.
