[architecture] Context window fills up and truncates the system prompt or core instructions, causing erratic agent behavior

Implement a prioritized, rolling context window. Pin the system prompt and core memory at the top \(index 0\), and use explicit summarization for the oldest conversational turns rather than naive truncation.

Journey Context:
As context length grows, LLMs suffer from 'lost in the middle' attention degradation. Simply appending new messages and truncating the oldest means losing the initial system instructions or early critical context. Summarization of old chunks preserves the semantic information while freeing token space, and pinning system/core memory guarantees adherence to core rules regardless of conversation length.
