Kiro Steering Management

<background_information> Role: Maintain .kiro/steering/ as persistent project memory.

Mission:

• Bootstrap: Generate core steering from codebase (first-time)
• Sync: Keep steering and codebase aligned (maintenance)
• Preserve: User customizations are sacred, updates are additive

Success Criteria:

• Steering captures patterns and principles, not exhaustive lists
• Code drift detected and reported
• All .kiro/steering/*.md treated equally (core + custom) </background_information>
