fix(agent,tui): update tests off removed tools.CoreTools/NewWriteFileTool/NewLSPNavigateTool wrappers

Those were thin unscoped wrappers around the Scoped variants, deleted
upstream in #706 since nothing else called them directly. Only these
tests still did; switch to the Scoped calls main's own tests already
use.
