How can I modify a workflow without impacting in-progress tasks?
I noticed that some changes (not exactly sure what changes) to a workflow can cause an error to any pending tasks of that workflow. When trying to perform a pending task after workflow modification, the error states that an incompatible change has occurred and prevents any further action to the task. The task stays in the user task list and cannot be removed.
What is the best way to prevent this issue? Also, can I query frevvo to find all pending tasks for a given workflow?

When you modify a workflow such that it changes the flows base schema, the xml of the saved task does not conform with that schema anymore. So frevvo cannot reload the flow with old data into new fields. Please see this doc section which explains the same concept.
Use the Search feature available on frevvo task lists to query for the tasks after entering required criteria.
