APR-Lite Stewardship Mode: Declaration Sealed Governance Primitive

This document is the formal declaration of APR-Lite's transition from builder-owned to operator-owned stewardship mode. It defines allowed and prohibited changes, the amendment protocol, long-term stewardship contacts, and the governance primitive closing statement. The substrate is sealed. The manifest hash is 64edea792d4932022f912ac9be7163d0f1765c872c57f9c4728be6e0a3d007ef. APR-Lite is no longer a development project — it is a governance primitive.
