dsh-memory-s3: Cloud-Based Cross-Session Memory Plugin

This is a cloud-based cross-session memory plug-in designed for DeepSeek Harness, using S3-compatible storage (such as AWS S3 or MinIO) to enable persistent memory and cross-device sharing. It employs a structured memory model and supports semantic retrieval, local caching, backlink indexing, and file attachment management. To ensure security, all write operations are subject to mandatory approval gates. The plug-in has no GUI configuration; S3 credentials must be managed via environment variables, and it provides a set of tools for adding, deleting, updating, retrieving, and synchronizing memories.
