Standalone RAG backend: hybrid search (pgvector + ParadeDB BM25 + LightRAG graph) with 4-mode rerank (CPU TEI + AMD gfx1151 GPU sidecars: BGE, Qwen3-Reranker 4B/8B) and GLiNER NER fast-mode. FastAPI on :5050. Bind-mount persistence.

Semantic duplicate bug-report detection running fully in the browser — Qwen3 embeddings (recall) + Qwen3 reranker (precision) on WebGPU via Transformers.js
