// VibeCoding Athena SessionStart hook v9.6
// 协议: hookSpecificOutput.{hookEventName: "SessionStart", additionalContext}
// 参考: https://code.claude.com/docs/en/hooks#sessionstart
//
// 设计 (铁律 8 索引先行):
//   1. 唯一 IO: read .ai_state/_index.md (frontmatter)
//   2. 注入 context-essentials.md (静态文本)
//   3. 注入 _index.md 关键字段摘要 (path/stage/sprint/counts/active_goal)
//   4. effort=max 时跳过 PACE 状态注入 (高 effort 模型自己探索)
//   5. 不预加载 tasks/design/progress 内容
