6c17fa2a5e 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.

4c76191fec 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

9a54ef214e 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.

746995f436 Merge 'Property FaultyQuery should fail if we encounter an error that is not expected' from Pedro Muniz
If we use `Assumption` here, the simulator just goes to the next
property instead of halting here.

1b52b5c764 Merge 'chore: update rust to version 1.88.0' from Nils Koch
This PR updates to version Rust 1.88.0 ([Release
notes](https://releases.rs/docs/1.88.0/)) and fixes all the clippy
errors that come with the new Rust version.
This is possible in the latest Rust version:
```rust
if let Some(foo) = bar && foo.is_cool() {
  ...
}
```
There are three complications in the migration (so far):
- A BUNCH of Clippy warnings (mostly fixed in
https://github.com/tursodatabase/limbo/pull/1827)
- Windows cross compilation failed; linking `advapi32` on windows fixes
it
  - Since Rust 1.87.0, advapi32 is not linked by default anymore
([Release notes](https://github.com/rust-
lang/rust/blob/master/RELEASES.md#compatibility-notes-1),
[PR](https://github.com/rust-lang/rust/pull/138233))
- Rust is more strict with FFIs and aligning pointers now. CI checks
failed with error below
  - Fixed in https://github.com/tursodatabase/turso/pull/2064
```
thread 'main' panicked at
core/ext/vtab_xconnect.rs:64:25:
misaligned pointer dereference: address must be
a multiple of 0x8 but is 0x7ffd9d901554
