Sibling Eviction for v3 transactions

The idea behind ephemeral anchors includes this notion, where their utilization necessitates implicit sibling eviction. Essentially, this delineates a feature into distinct components, each addressing a specific aspect of the overarching functionality. Ephemeral anchors, by design, are temporary constructs that, when used, naturally lead to the eviction of related elements, streamlining the process and enforcing a form of automatic management within the system's architecture. This approach simplifies the implementation, ensuring that resources are efficiently allocated and that the system remains optimized without manual intervention.
