Update tscircuit dependencies and disable Bun lockfile

[hz19880404-tech]

Summary

/claim #79

• Updated the tscircuit and circuit-json related dependencies to their current compatible npm releases.
• Removed bun.lock as requested.
• Kept the existing bunfig.toml configuration with [install.lockfile] save = false, so Bun does not save a new lockfile during install.
• Left the Vite/React/tooling stack unchanged to keep the Vercel deployment surface area minimal and avoid introducing unrelated framework changes.

Notes

The change is intentionally scoped to dependency refresh plus lockfile handling for the Vercel deployment issue described in #79.

Verification

• Confirmed the diff only changes package.json and removes bun.lock.
• Confirmed the fork is 2 commits ahead of tscircuit:main and 0 commits behind before opening this PR.

I do not have Vercel project access from this environment, so I cannot directly confirm the production Vercel deployment, but the repository-side changes requested in the issue are included.
