It'll be useful to understand what runtime environment a worker is operating in now that we support bun. We should include in the worker heartbeat some info about whether we're on node or bun, what version we're at, etc. If we can discern if we're inside a Vercel instance or similar, that would also be worth differentiating.
Sending this should be opt-out.
This will require an API PR to add the info to the worker heartbeat, and coordinating with server/obs teams to get it plumbed through.
