Update circuitjson dependencies for Vercel

[nguyenduchuyhd]

/claim #79

Summary

• Updated the tscircuit/circuit-json dependency stack to current published versions, including circuit-json, tscircuit, viewer packages, and conversion packages.
• Removed the tracked Bun lockfile and ignored future �un.lock / �un.lockb files so the repo matches the requested lockfile-disabled setup.
• Added explicit Vercel install/build settings so deployments use Bun after the lockfile is removed.
• Migrated the Biome config to the installed Biome 2 schema so the existing format script continues to work after dependency updates.

Verification

• �un run format passes.
• Clean install check: removed
  ode_modules, ran �un install, confirmed no �un.lock or �un.lockb was recreated.
• �un run build passes with Vite 8 and outputs dist/.

Note: �unx tsc --noEmit still reports pre-existing errors in docs/reference-implementation.tsx, which appears to be a standalone reference file outside the build path.
