Related issue: N/A (found by reading the code; reproduced on main at 6b33dff)

What changed?
In the Query branch, also emit _extract_llm_text(llm_output) as an assistant message (sequence_id <exchange_id>_response). Current schema (no ai_blocks, llm_output NULL) is unchanged.

Why?
Sensor/adr_sensor/parsers/warp_parser.py:218-223. On the legacy schema (ai_blocks present) each exchange's model output is in ai_blocks.output. The parser uses it for ActionResult exchanges but in the Query branch only emits the user message, so the assistant's reply to every user prompt is dropped.

How did you test it?

• Reproduction: scratchpad/warp_query.py (one Query exchange with ai_blocks output "Let me check with ls."): main prints only user 'what is in this dir?'; branch also prints assistant 'Let me check with ls.'. New test test_legacy_schema_retains_query_response; existing test_parses_conversation_content updated (its fixture already stored "reply for ex-1" in the Query exchange's llm_output and the old assertion len==2 encoded the drop; now 3 with the reply checked). Main: 2 failed; branch: all Warp tests pass.
• Test suite: py3.14 609 passed; py3.9 609 passed.
• Not tested: against a real legacy Warp DB (none with ai_blocks available); semantics inferred from the parser's own ActionResult handling of the same column.

Potential risks
The change only affects the input described above; other paths go through the same code as before, and the component's existing tests pass.
