[Feature] : Add a cookbook using Unstructured with Moss

[CoderOMaster]

Parse PDFs, Word docs, HTML, images, and other file formats with Unstructured and index the extracted content directly into Moss for semantic search. The cookbook demonstrates a full ingestion pipeline from raw files to a queryable Moss index with document chunking, metadata preservation, and incremental upserts.
