Struct PromptCache 

pub struct PromptCache { /* private fields */ }

Single-slot memo for the rendered system prompt, keyed by a hash of the inputs. Most consecutive turns in a session pass identical inputs (template, turn-driver-preamble-derived execution_prompt / tool_names, plus context contributions), so a one-slot cache hits repeatedly and avoids the section-by-section Vec<String>::join work in PromptTemplate::render.
