A passing build test reported "All checks passed" and threw away the
run's actual node outputs. TestResultCard gains an `output: str` field
(pretty-printed JSON of the last node that produced anything, "" when
none); handle_test_and_repair's success card now populates it via a new
_terminal_output(per_node) helper.
_terminal_output is deliberately status-agnostic (no node.status filter):
per-node status spellings differ by source ("success" vs "succeeded"), and
a status filter that silently misses would defeat the point of the card.
FakeDifyPort (tests/unit_tests/core/dify_builder/fakes.py) gains a
settable run_outputs dict, seeded onto the success-path NodeOutput's
outputs, so tests can assert on what the card shows without hand-rolling
a Run.
