Expand description

Read API shared by the read-write EdgeShard and the read-only follower shard.

Every method takes its edge request type from [crate::requests]; the blanket impl converts it into the internal request the read logic executes.

A shard only implements the crate-private snapshot provider; this trait comes for free through a blanket impl whose methods build an [EdgeReadView] from that snapshot and run the shared logic, so the read code is never duplicated and the snapshot plumbing stays invisible to crate users. Sealed: cannot be implemented outside the crate.
