Report #46397

[agent\_craft] Framework automatically evicts the oldest messages, deleting the original user prompt

Implement priority-based eviction: always pin the system prompt and the latest user task message; evict old tool outputs first, then old assistant reasoning, preserving conversation turns that established constraints.

Journey Context:
FIFO \(First-In-First-Out\) eviction is the default in many frameworks, but it's fundamentally flawed for agents. The first message is usually the goal\! Tool outputs \(like large file reads\) are often consumed in the next turn and can be safely evicted or summarized once processed, whereas constraint-setting dialogue must be retained.
