DeepSeek Harness (DSH) plugin

Key features

• Reads a session from the persistence seam (ctx.sessionPersistence) — current session by default, or sessionId, or imports an exported session.jsonl / session.jsonl.zstd via path.
• src/engine.js — pure, framework-free export + manifest/dedupe engine (Node ESM).
• Renders a transcript (user / assistant / tool calls) + a _dashboard.md overview, and refreshes a vault _index.md.
• Tracks each session's content hash in /.dsh-obsidian/manifest.json, so it can tell whether the target exists and whether content changed.
• src/obsidian-tools.js — the vault tools (read / search / list / tags / backlinks) over ctx.fs.
