DeepSeek Harness Plugin: maxmilian/dsh-forge

`maxmilian/dsh-forge` is a DeepSeek Harness plugin that connects to self-hosted Gitea or Forgejo instances via the REST API, providing agents with read-only access to repositories, issues, pull requests, and Actions. Core features include instance information queries, repository search, issue/PR detail reading, Actions log viewing, and localization support. Installation requires configuring `DSH_FORGE_URL` and a token. In the current version (v0.3), all tools perform read-only operations, support safe parallel execution, and are suitable for code review and automated operations scenarios.
