Our simulator is currently limited to concurrency of one. This
introduces a much less sophisticated DST with focus on finding
concurrency bugs.
Closes#2985
After the fix in #3023, the transaction isolation fuzz test now
incorrectly takes a shadow snapshot of the DB state too early - before
it is determined that the connection successfully started a read
transaction.
Fix: take the snapshot after we've verified that the read TX started.

If both of the following are true:
1. All read locks are already held
2. The highest readmark of any read lock is less than the committed max
frame
Then we must return Busy to the reader, because otherwise they would
begin a transaction with a stale local max frame, and thus not see some
committed changes.

Value conversion to float for math functions work in a more strict way
than general numeric conversion. For example, valid prefixes that can be
converted to a integer, like `"44s"` will be converted to `Value::Null`
instead of trying to recover like the math operators.

Closes#3012
Particularly we were tracing `ImmutableRecord` / `BTreeKey` which would
then trace the bytes of records. These are super super hot paths and I
think we can probably remove even more to under debug assertions so we
dont eat those atomics/branches all the time.
This PR also introduces the `tracing_release` feature, which turns all
`trace!` and `debug!` macro invocations to noops at compile time, and
makes that feature available for all bindings.
it also removes the unused `lru` dependency, and cleans up the makefile
a bit

This PR adds OPFS support to the sync package and also restructure it in
the similar fashion as in #2799
The structure for sync packages looks like this:
1. `@tursodatabase/sync-common` - package with common abstract TS code
shared between node and browser
2. `@tursodatabase/sync` - native package for node
3. `@tursodatabase/sync-browser` - browser package
Also, additional package `@tursodatabase/database-browser-common` was
extracted to share some common OPFS related code between
`@tursodatabase/database-browser` and `@tursodatabase/sync-browser`
packages.
Also, this PR moves JS bindings for sync directly to the
`bindings/javascript` folder because this allows to use all 7 packages
within same workspace.
Closes#3014
Closes#2997
Fixes issue #2997 where connection 2 cannot see tables created by
another connection 1, because `Connection::query()` was not checking
whether its copy of the schema was stale.
