Adds a high-16-bit-prefix landblock residency check used as the teleport worldReady gate — true once the destination landblock's terrain+cells have been registered via AddLandblock, regardless of whether the caller passes a canonical (0xFFFF), cell-resolved, or bare landblock id. Two TDD tests confirm: false before registration, true after, and that a cell-resolved id on the same landblock returns true. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
