memoryd: Honcho responses for M5c-2's read path, recorded from rift (M5c-2 task 00)

Workspace search with a limit and with no match, conclusion queries for the owner's and another
agent's peer, and what a workspace that does not exist answers to search, query, chat and delete.
Recorded through roncho 1.0.0's blocking client in the throwaway workspace boxmaker-plan-probe,
deleted afterwards.

@@ -5,3 +5,14 @@ design model for M5c-1, in a throwaway workspace, `boxmaker-plan-probe`, created
 afterwards. Each request is exactly what `roncho` 1.0.0's blocking client sends. Each file is
 `{"request": {"method", "path", "body"}, "response": {"status", "headers", "body"}}`. The fake
 Honcho server in `memoryd`'s tests answers from them. Do not edit.

+Files 30 to 37 were recorded the same way on 2026-09-28 for M5c-2, in the same throwaway workspace
+(again deleted afterwards), through a proxy that allowed no other workspace. What they show:
+
+- Search has no relevance cutoff: a query with no match (31) still returns the nearest messages.
+- A search or a conclusion query in a workspace that does not exist answers 200 with no hits (34,
+  35); only chat (36) and delete (37) answer 404.
+- The duplicate tea messages in 30 and 31 are real: the recording ran twice into one workspace.
+
+A chat at `reasoning: low` was recorded too and left out: on rift it returned the dialectic
+model's raw tool-call markup as its answer, not an answer.
