[architecture] Offloading current task state to vector DB too early to save context tokens

Keep the active working set \(current task, recent tool outputs, immediate scratchpad\) strictly within the LLM context window. Only offload to the vector store when the context window exceeds a high-water mark \(e.g., 75% capacity\) or when a distinct sub-task completes.

Journey Context:
A common optimization is to aggressively summarize or embed intermediate steps to keep context windows small and cheap. However, LLMs require contiguous, high-fidelity context to reason about complex, multi-step tasks. If you embed a tool output and then retrieve it later via RAG, you lose the exact sequence and surrounding context, leading to 'lost in the middle' failures or broken logical chains. The context window is for reasoning; the vector store is for retrieval.
