chore: update circuit deps and remove bun.lock for Vercel deploy

[sungdark]

Closes #79

/claim #79

What changed

• removed tracked bun.lock and ignored it (lockfile saving is disabled in bunfig.toml)
• updated key dependencies to latest versions (including circuit-json, tscircuit, and related exporters/viewers)
• added missing @react-hook/resize-observer dependency required by updated graph dependencies

Verification

• NODE_OPTIONS=--max-old-space-size=4096 npm run build completes successfully
• build output generated without unresolved import failures (the previous @react-hook/resize-observer resolution error is fixed)

This follows the bounty guidance to remove lockfile usage and validate deploy/build health.
