Builds failed with an empty graph when the generator LLM wired downstream
references to an HTTP-request node's output as `{#node.response#}`. HTTP-request
nodes expose only {body, status_code, headers, files} — never `response` — and
the reference-repair pass only rewrites to a node's SOLE output, so with four
outputs the ref stayed unresolved: structural validation failed
(runner.py:646 UNRESOLVED_REFERENCE), generate_workflow_graph returned no graph,
and build_nodes produced an empty build ("Couldn't build the workflow").
Add a targeted, unambiguous output-name alias (http-request `response` -> `body`,
the response body) applied in _reconcile_variable_references before the
sole-output fallback, guarded so it only rewrites when `body` is actually
declared. Extensible via _OUTPUT_ALIASES for future known-wrong names.
