fix: update deps and configure bun vercel build

[nguyenducshuy]

Summary

• update the tscircuit / circuit-json dependency stack to current published versions used by the app
• add direct peer dependencies required by the newer @tscircuit/runframe / @tscircuit/core stack so Vite can bundle cleanly
• remove the tracked Bun lockfile and ignore future bun.lock / bun.lockb files
• add Vercel project config so deployments keep using Bun even after removing the lockfile

Verification

• npx --yes bun install
• confirmed bun.lock and bun.lockb were not regenerated
• npx --yes bun run build

Notes: local vercel build --yes could not run because the local Vercel CLI token is invalid, so I verified the same configured install/build commands directly.

A member of the Team first needs to authorize it.
