Fix silent exit when a query runs on a connection left idle by a prompt

An idle Bun.SQL connection does not keep the event loop alive. After an
inquirer prompt released stdin, the next query let Bun exit with code 0
mid-query: `schema` never applied confirmed destructive changes, and
`admin` table views exited instead of showing results. Hold the loop open
for the duration of every query and transaction.
