[architecture] Agent repeating outdated instructions or facts from early in the context window instead of adapting to new constraints

Implement a dynamic context manager that actively overwrites or invalidates previous instructions and facts in the working memory when contradictions are detected, rather than just appending new instructions to the end of the prompt.

Journey Context:
LLMs suffer from lost-in-the-middle syndrome and primacy bias. If you tell an agent to use Format A, then later tell it to use Format B, appending the new instruction often still results in Format A because the original instruction remains prominent. The tradeoff is the compute required to rewrite the context string versus the risk of contradictory behavior. Mutating the context window to remove or replace obsolete instructions is essential for maintaining a coherent current state.
