[codex] Add deterministic decoupling cap row layout

[dclawd88]

Summary

/claim #15

• Bypass the generic inner partition packer for partitions marked partitionType === "decoupling_caps".
• Lay decoupling capacitors out in a deterministic centered row using natural component ordering.
• Use decouplingCapsGap with a chipGap fallback, and account for fixed 90/270 degree rotations when calculating row width.
• Add focused solver tests for ordering, centering, gap fallback, and rotation-aware spacing.

Why

The pipeline already identifies decoupling capacitor groups and separates them into decoupling_caps partitions, but those partitions still went through PackSolver2. That generic packing can produce cluttered decap clusters. A narrow deterministic row path makes the decoupling-cap case predictable without changing default partition behavior.

Validation

• npx --yes bun test tests/PackInnerPartitionsSolver/SingleInnerPartitionPackingSolver.test.ts
• npx --yes bun run format:check
• npx --yes bun run build
• git diff --check

I also ran npx --yes bun test; the suite reached 20 passing tests and 1 skipped test, then stopped on an existing dependency export issue: convertCircuitJsonToSchematicSimulationSvg is not exported from circuit-to-svg/dist/index.js.

[vercel]

Someone is attempting to deploy a commit to the tscircuit Team on Vercel.

A member of the Team first needs to authorize it.

Status note: test, format-check, and type-check are green. The remaining red status is the Vercel deployment authorization gate that requires a tscircuit team member to authorize the fork deployment.
