Update tscircuit deps and remove Bun lockfile

[ar-amk]

/claim #79

Summary

• Updated the tscircuit/circuit-json viewer and exporter stack to current published versions, including tscircuit, circuit-json, the PCB/schematic/3D viewers, and related export packages.
• Removed the tracked bun.lock so the repo matches its existing bunfig.toml setting of [install.lockfile] save = false.
• Added bun.lock and bun.lockb to .gitignore to prevent accidental lockfile reintroduction.

Validation

• bun install completed and did not recreate bun.lock or bun.lockb.
• bun run format
• git diff --check
• bun run build passed. Vite emitted the existing browser external/chunk-size warnings, but completed successfully.

Note

I also tried bunx tsc --noEmit; it currently fails on pre-existing docs/reference-implementation.tsx demo references such as ./use-store, src/parse-kicad-mod-to-circuit-json, convertCircuitJsonToTscircuit, and createSnippetUrl. I did not change that docs file because it is outside this dependency/build-hygiene scope.

[vercel]

@ar-amk is attempting to deploy a commit to the tscircuit Team on Vercel.

A member of the Team first needs to authorize it.

[ar-amk]

Vercel is showing a GitHub authorization failure URL rather than a build error on this fork preview. I verified the production build locally with bun run build; it completed successfully with only the existing dependency externalisation/chunk-size warnings noted in the PR body.
