dsh-memories: Dual-Ledger Cross-Session Memory Plugin for DeepSeek Harness

The `dsh-memories` plugin in DeepSeek Harness uses a dual-ledger system to address agents' challenges in cross-session memory and progress tracking. It automatically extracts long-term facts and project progress, and provides noise filtering, memory decay, and backup capabilities, while supporting LLM integration and manual command control. Developers can manage the ledgers through slash commands or tool functions, making it suitable for complex project scenarios that require long-term context maintenance.
