📄 Description

Document the new Projection Streaming model across LangGraph, LangChain, and Deep Agents, while preserving Mode Streaming as the lower-level Pregel stream mode reference.

Adds LangGraph streaming docs for overview, projection streaming, protocol, remote streaming, in-process vs remote behavior, custom transformers, and EventLog vs StreamChannel. Adds consolidated LangChain and Deep Agents streaming projection pages, updates navigation and redirects, and refreshes related cross-links so users land on the recommended application-facing streaming docs.
