bun is a completely separate piece of code - it uses JavaScriptCore rather than v8, there's no 'wrapper' involved. I strongly suspect that what you saw was from running a script with a #! line that specifies node, because bun honours #! lines by default. If you use <bun run --bun> that will tell it to use bun instead when it sees a node shebang.
