//! Long-lived memory tools: [`memory_write`](MemoryWriteTool), [`memory_update`](MemoryUpdateTool),
//! [`memory_read`](MemoryReadTool), [`memory_search`](MemorySearchTool).
//!
//! Default layout (OpenClaw-style, paths adjusted): **`.agent/memory/YYYY/MM/dd.md`** for append-only daily notes,
//! and **`.agent/memory/MEMORY.md`** for curated long-term summary. See [`MemoryContext`].
