dsh-database-manager: DeepSeek Harness Database Management Panel

dsh-database-manager is a database management plugin for DeepSeek Harness, designed to address the issue of developers frequently switching between interfaces. It centrally manages data sources through a sidebar and provides two panels: MySQL/SQLite and Redis. The MySQL/SQLite panel supports browsing, schema editing, SQL execution, search, and bulk operations, and is compatible with versions 5.5 and above; the Redis panel supports directory tree browsing, editing multiple data types, and command-line operations. The plugin specifically optimizes loading strategies for large databases and supports SQL import/export as well as zero-dependency installation. By leveraging protected Agent tools, it enables one-stop data querying, schema changes, and Redis key-value management within the DSH interface.
