Test fanout-solver #90 in Core

[ShiboSoftwareDev]

Summary

• replace Core's published @tscircuit/fanout-solver@0.0.35 dependency with the exact head commit of Reuse preloaded fanout trace identities fanout-solver#90
• pin commit 5011b76e9c724c747037e0b47a94fde64dd04860
• make no Core source or test changes, so Core CI and snapshot artifacts measure only the solver dependency change

Why this is needed

fanout-solver#90 stops preloaded fanout traces from being returned again as newly emitted copper. The solver-level regression passes, but Core is the phased host that accumulates fanoutTraces, converts them into Circuit JSON, and exercises the wider breakout/fanout matrix. Pinning the exact PR head lets Core's full type-check, test shards, smoke test, and snapshots reveal integration regressions before the solver PR is merged or published.

This is a temporary integration-test pin. After #90 is merged and released, Core should return to an exact published version.

Core CI result

✅ The exact #90 head passes Core type-check, smoke test, formatting, and all ten test shards. No Core snapshot regression was reported.

Local verification

• bunx tsc --noEmit
• 31 focused fanout/breakout tests passed, including tests/repros/repro-am62l-lpddr4-two-bus-fanout.test.tsx
• tests/breakout/breakout-insufficient-fanout-space-error.test.tsx passed when rerun alone after timing out only while both large dependency suites were competing for local CPU
• git diff --check
