Implement a file-based persistent memory system that allows the AI to
retain knowledge about users, feedback, projects, and references across
sessions. Memory files use YAML frontmatter with markdown body, stored
at ~/.claw/projects/<workspace-hash>/memory/.
Key components:
- MemoryStore data layer with FNV-1a workspace fingerprinting
- MemoryRead/MemoryWrite tools with security hardening (path traversal,
symlink, absolute path, and size limit protections)
- System prompt injection of MEMORY.md index with prompt injection
mitigation (fenced code block + trust-lowering notice)
- autoMemoryEnabled config option (defaults to true)
- Doctor health check for auto-memory state
- /memory command enhancement showing persistent memory info
Tested end-to-end with Zhipu GLM-4-Flash via OpenAI-compatible routing.
