enhance: update history fetch state + token count on simple tasks

[a7m-1st]

Description

1. Return token updates
2. Use the data from the history api as much as possible (refetches on each update rather than local optimistic updates)

Known bugs

• When running a new task the "New Project" is actually being replaced. Thus the view on "2" tasks, but it disappears once the title is generated.
