Output parser crashes on a top-level JSON array fallback

[Aburke225]

When the LLM returns a top-level JSON array instead of an object, output_parser.py calls .items() on the parsed value and raises AttributeError: 'list' object has no attribute 'items'. The fallback path should handle array responses.

The covering test is marked @pytest.mark.xfail referencing manifest id H-02 — remove the marker as part of the fix.

Relevant files:

• rag/generator/output_parser.py
• tests/unit/test_output_parser.py

Estimated effort: 2–4 hours

Hey,I can take this one. I checked the current parser and the xfailed test for the JSON array case, and the issue looks pretty contained to output_parser.py plus the existing parser test. I’ll work out the expected array handling and update the test/remove the xfail along with the fix.
