Kiro CLI adds compaction hooks, session credits tracking, and environment settings

This Kiro CLI update introduces PreCompact and PostCompact hooks for conversation compaction and displays session credits used in /usage, the status line, and workflow step rows. It adds support for shipping default settings for an environment, an opt-in session recap, sub-agents reading parent memories, and groups notifications into a single row.
