S3 Vectors RAG workload

Vector search without a vector database — Amazon S3 Vectors, Bedrock embeddings, and a serverless RAG app.

Create vector buckets and indexes with Terraform, then run RSS ingest, Bedrock embeddings, similarity search, reranking, and LLM answers in one application.

Includes production patterns for least-privilege IAM, JWT auth, CORS, throttling, and scheduled automation.
