Hybrid search with context assembly for LLM.

adjacentChunks - Include N chunks before/after matches (default: 0). singleSourceMode - Only include chunks from most relevant source. hydrationMode - Controls whether high-level chunk payloads are returned as full content, lightweight previews, or omitted entirely. previewMaxBytes - Maximum UTF-8 bytes per chunk preview when hydrationMode is SearchHydrationMode.preview.
