deepseek-harness plugin

Key features

• This plugin treats a user-chosen or preconfigured Git repository as the memory store.
• repoPath - the local Git checkout that stores memory and skills.
• auth.mode"ssh" - use ssh or a custom sshCommand.
• No automatic prompt injection yet.
• It can write session notes, branch-specific records, and reusable skill drafts into that repo, then commit them as ordinary Git history.
