Module declare 

Reading a virtual table’s declaration and a pragma’s argument.

Invariant: nothing here touches a database. These are four pure functions over types this crate already owns, a Declaration and a PragmaArgument, and they are here rather than in a connection crate because both engines need them and neither should have to depend on the other to get them.

They lived in inillucent-session, which is the old engine’s connection, and the new engine’s statement path imported them from there. That was the last thing tying the new engine to the old one that was not itself an engine: two helpers that parse text. Moving them down removes the edge without changing a caller, because inillucent-session re-exports both under their old paths.
