DSH Semantic Search

A DeepSeek Harness (dsh) plugin for local semantic code search. Builds a fragment-level index of a workspace (symbol-aware chunking for many languages), computes local embeddings (lightweight lexical TF-IDF feature vectors by default, or a configurable OpenAI-compatible embedding endpoint), and answers natural-language queries with hybrid retrieval (vector cosine + BM25, fused with reciprocal-rank fusion). Ships dsh tools sema_search / sema_reindex / sema_stats plus a stand-alone CLI.
