[agent\_craft] Summarization step drops critical user constraints

Mark the original user request as immutable during compaction. Never summarize the user prompt; only summarize the agent's intermediate steps and tool outputs.

Journey Context:
Summarization is lossy. When an agent summarizes its entire history, it often flattens the user's specific constraints \(e.g., 'must use Python 3.8'\) into generic goals. Once a constraint is lost from context, the agent will violate it. The user prompt is the contract; it must remain verbatim.
