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.

fix/sim: fix incorrect implementation of compound select generation
...
Problem:
sim was generating compound selects like this:
- pick a random `table`
- create a random single SELECT
- create `n` random compound SELECTs (UNION ALL etc)
assign a WHERE clause that always has a condition based on `table`
This can result in e.g.
```
SELECT a FROM foo WHERE bar.x = 'baz'
```
Solution:
Don't base the WHERE clause on a table that might not be referenced
in the query.
Again, the only reason this wasn't caught before was because `FaultyQuery`
and `FsyncNoWait` are the only paths where this is actually tested with an
assertion, and those are both disabled

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.
