v0.3.2 — ARPM-derived Local RAG for DSH

First public release of the independent ARPM-derived Local RAG branch for DeepSeek Harness.

Highlights:

• Model-invoked search_local_memory tool; no provider patch and no forced prompt injection.
• Local hybrid retrieval: vector + BM25+ with deterministic RRF fusion.
• Knowledge uploads and session-isolated native DSH compaction summaries.
• PDF/DOCX/TSV/CSV/TXT/Markdown/JSON/HTML ingestion with provenance.
• Editable, deletable, versioned and rollback-capable source documents.
• Safe local-rag:// source references and model-visible source preview.
• Explicit local embedding model download/start/stop/autostart lifecycle.
• Lexical fallback when the vector lane is unavailable.

Validation: build, package, and 87 automated tests passed.
