Change default thunk pruning level to 'omit'

Although the parser+generator is relatively mature, the surface area of
source changes with the potential to cause broken generated mocks is
still quite large. To improve the developer experience and initial setup
process, this change flips the default thunk pruning level from 'stub'
which still generates *declarations* for unused types, to 'omit' which
only creates mocks for referenced types in tests.
