memory_tree walk: `query` is required

Error message

memory_tree walk: `query` is required

What it means

The memory_tree walk entry point found no "query" string in the args. run_fast_walk requires a natural-language query to drive the E2GraphRAG deterministic retriever; this guard fires before limit/hops parsing.

//!
//! Both modes now resolve to [`fast_retrieve`] — the E2GraphRAG, LLM-free
//! retriever. It returns a structured [`QueryResponse`] of ranked evidence
//! (no synthesized prose); a higher-level context agent composes the answer.

Solutions

1. Pass a non-empty "query" string describing what to retrieve
2. Check the tool call did not drop fields mid-serialization
