dsh-doc-reissue: Document Reissuance Tool

dsh-doc-reissue is a workflow plugin for the DeepSeek Harness (DSH) platform, maintained by user uckkk. Implemented purely in Node.js with no network dependency, it is designed to generate reissue plans for managing household documents and certificates. The plugin provides the `doc_reissue` tool, which users can install via the terminal and invoke directly in a session. As a locally running tool, it follows DSH's "everything is a plugin" philosophy, and note that it should be run with the current process permissions.
