test: remove non-functional prompt dependency test

Removed test_prompt_with_dependency since prompt dependency support
is not yet fully implemented. The infrastructure is in place but
requires additional work to function properly.

This test was added for coverage but doesn't actually exercise the
dependency resolution code paths effectively.
