Adds a new end-to-end app, RAG on Edge, demonstrating Retrieval-Augmented Generation running fully on-device

The pipeline indexes the Gemma 4 technical report PDF and answers questions about it using:

  • Qdrant Edge for vector search engine
  • EmbeddingGemma2 (embeddinggemma-2-740m) for retrieval embeddings
  • Gemma 4 E2B for generation

Both engines run on a local GPU backend via LiteRT-LM.
