Refine diagram: update representative projects and Embedded LLM description

- LLM-Embedded: MAGMA→Letta, add "Extra API cost" annotation
- MCP Server: MemCP→claude-mem
- Embedded LLM: remove "small context", highlight extra API call per memory op
Updated in README (EN/ZH), drawio source, and exported JPG.
