as we have DROP table now, if we want to generate extensional queries eagerly, without affecting how we document interactions with MVCC, we need to travel forward in time and shadow queries eagerly so we can generate queries correctly. This involves cloning the tables unfortunately which is inneficient but correct

fix/sim: prevent sim from trying to create an existing table or index
...
We recently merged a change that panics the sim on parse errors, because
not doing so has masked many scenarios where the sim unintentionally
creates incorrect sql and we just ignore it.
We already have Property::DoubleCreateFailure to assert that the same table
cannot be created twice, so this should not hide any bugs.

parser: Distinguish quoted identifiers and unify Id into Name enum
...
This commit replaces the `Name(pub String)` struct with a `Name` enum that
explicitly models how the name appeared in the source either as an
unquoted identifier (`Ident`) or a quoted string (`Quoted`).
In the process, the separate `Id` wrapper type has been coalesced into the
`Name` enum, simplifying the AST and reducing duplication in identifier
handling logic.
While this increases the size of some AST nodes (notably `yyStackEntry`),
it improves correctness and makes source structure more explicit for
later phases.
