Stops the running task, if any, and drops queued tasks. The last successful
value is kept and the status becomes "idle", so has_value_async() stays
TRUE and reading the reactive still returns that value. A task gated with
shiny::bindEvent() stays in that state until its next event, and an event
still waiting for an upstream async reactive is dropped; any other
task re-runs when a dependency changes. Interrupting a task that is
already executing requires a daemon pool with a dispatcher, which
pool_async() always uses; otherwise the result is discarded when it
arrives.
