[frontier] Naive context truncation or generic LLM summarization destroys operational agent state and breaks tool execution chains

Implement State-Machine Driven Context Eviction. Evict or summarize context based on semantic entity boundaries \(e.g., compress completed tool-call/result pairs, but preserve the current task's unfulfilled parameters and system constraints\).

Journey Context:
When agents hit context limits, developers often use simple sliding windows or ask the LLM to 'summarize the conversation.' This breaks because LLM summarization loses exact IDs, specific numeric values, or schema constraints required for subsequent tool calls. Entity-boundary eviction ensures that operational variables \(the 'stack' of the agent\) remain intact while compressing the 'heap' \(historical reasoning\).
