Module memory 

Memory - Core and Working Memory for Umi

TigerStyle: Three-tier memory architecture with explicit limits.

Memory Tiers

1. Core Memory (~32KB) - Always in LLM context
2. Working Memory (~1MB) - Session state, KV store with TTL
3. Archival Memory (unlimited) - Long-term storage (separate module)

Example

use umi_memory::memory::{CoreMemory, MemoryBlockType};

let mut core = CoreMemory::new();
core.set_block(MemoryBlockType::System, "You are a helpful assistant.").unwrap();
core.set_block(MemoryBlockType::Human, "User prefers concise responses.").unwrap();

let context = core.render();
// <core_memory>
// <block type="system">You are a helpful assistant.</block>
// <block type="human">User prefers concise responses.</block>
// </core_memory>
