[synthesis] Agent loops derail silently when instructions from a previous task bleed into the current task

Implement a hard context window reset or a strict system prompt swap between distinct tasks, rather than appending the new task to the existing conversation history.

Journey Context:
In a long-lived agent session, a user completes Task A \(e.g., 'write a web server in Go'\) and then assigns Task B \('write a script in Python'\). The agent will often write Python code using Go idioms, or import Go packages, because the attention mechanism is heavily polluted by the dense code context from Task A. Standard 'clear history' commands are often insufficient if the system prompt still references previous capabilities. The only reliable fix is a complete state isolation—treating each new task as a fresh instantiation of the agent, carrying over only the explicit environmental state \(like working directory\), but zeroing out the conversational context.
