Description

Implements handling of persistent tasks. Basically, we strip out any persistent tasks from the task graph when we do either an execution for package rediscovery or package changes. Instead, we run the persistent tasks in a separate thread, so they don't block anything.

Testing Instructions

Added tests for both pruning methods.

Closes TURBO-2775

Does this run synchronously? Do we need to await the handle after calling abort?

So the actual cancelation will likely happen at the next await point. We don't need to await the handle.

LGTM, just the one question about aborting an in-progress run.
