Update dependencies and remove Bun lockfile

[jorgeschulz]

Summary

/claim #79

• updates the tscircuit/circuit-json viewer dependency stack to the current published package versions
• migrates biome.json to Biome 2 after upgrading @biomejs/biome
• removes the committed bun.lock and ignores future bun.lock/bun.lockb files, matching the existing [install.lockfile] save = false config
• removes vite-tsconfig-paths and uses Vite 8 native resolve.tsconfigPaths support instead

Verification

• npx --yes bun@latest install
• npx --yes bun@latest run build
• npx --yes bun@latest x biome check biome.json vite.config.ts
• git diff --check
• confirmed no bun.lock or bun.lockb was regenerated after install

Notes

• The Vite build passes locally with Vite 8.0.12. The remaining output is the existing large chunk warning plus a browser-compat externalization warning from manifold-3d.
• I also tried npx --yes bun@latest x tsc --noEmit; it fails in existing docs/reference-implementation.tsx references to missing local modules/symbols, which are outside this dependency/build hygiene change.

AI-assisted with Codex; I reviewed the diff and ran the checks above before opening this PR.
