Set a deadline for the complete lookup.

req.setTimeout(10000) measures socket inactivity after connection. It does not bound connection setup or a response that sends data at intervals shorter than 10 seconds. In either case, widget compilation can still hang instead of reaching the CI error or local warning. Use an absolute timer that destroys req, and clear it when the lookup settles. (nodejs.org)

Review comment at @compile-partial.js at line 49:
Replace the socket-inactivity timeout on req with an absolute deadline that
destroys the request if the complete lookup exceeds 10 seconds, including during
connection setup or intermittent responses. Clear the deadline when the lookup
settles.

Not changing this: the socket timeout already covers a stalled connection, and a slow trickle from docs.redpanda.com is unlikely enough that an extra overall timer is not worth it here.

@JakeSCahill Understood. You accept the residual risk of having no overall deadline for this lookup. I won’t press for an additional timer.
