[synthesis] Context window amnesia breaking downstream state constraints

Maintain an active constraints manifest injected at the top or bottom of every subsequent prompt, rather than relying on the original instruction surviving rolling context truncation.

Journey Context:
As context windows fill up, older messages are truncated or summarized. If an early constraint \(e.g., 'only modify files in /src'\) is dropped, the agent will confidently violate it later, thinking it's acting correctly. Standard conversation memory just summarizes text, which often drops strict rules. The right call is separating immutable constraints from transient chat history and re-injecting them persistently.
