test(smart-notes): spy on Agent.addRequest instead of createConnection

bun's stable node:https shim leaves globalAgent.createConnection
undefined (it exists only on canary builds), so the keep-alive-agent
test crashed on every stable runtime including CI. addRequest is the
portable interception point: every Agent-routed request enters it on
node and both bun lines.
