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.

This PR enables the use of an index as the iteration cursor for a point
or range deletion operation. Main changes:
- Use `Delete` opcode for the index that is iterating the rows - avoids
unnecessary seeking on that index, since it's already positioned
correctly
- Fix delete balancing; details below:
### current state
- a deletion may cause a btree rebalancing operation
- to get the cursor back to the right place after a rebalancing, we must
remember what the deleted key was and seek to it
- right now we are using `SeekOp::LT` to move to one slot BEFORE the
deleted key, so that if we delete rows in a loop, the following `Next()`
call will put us back into the right place
### problem
- When we delete multiple rows, we always iterate forwards. Using
`SeekOp::LT` implies backwards iteration, but it works OK for table
btrees since the cursor never remains on an internal node, because table
internal cells do not have payloads. However: this behavior is
problematic for indexes because we can effectively end up skipping
visiting a page entirely. Honestly: despite spending some debugging the
_old_ code, I still don't remember what exactly causes this to happen.
:) It's one of the `iter_dir` specific behaviors in `indexbtree_move_to`
or `get_prev_record()`, but I'm too tired to spend more time figuring it
out. I had the reason in my head before going on vacation, but it was
evicted from the cache it seems...
### solution
use `SeekOp::GE { eq_only: true }` instead and make the next call to
`Next()` a no-op instead. This has the same effect as SeekOp::LT +
next(), but without introducing bugs due to `LT` being implied backwards
iteration.

1. Add script that cleans simulator logs into just the SQL statements
2. Add script that bisects a set of SQL statements to find the minimal
prefix set of statements that fails SQLite integrity check
Closes#2999
The `run_once()` name is just a historical accident. Furthermore, it now
started to appear elsewhere as well, so let's just call it IO::step() as
we should have from the beginning.
Closes#3001

Resolves#2677
- Implements the modifier for Floor on the datetime object.
- Implements the modifier for Ceiling on the datetime object.
- Includes additional testing changes in testing/scalar-functions-
datetime.test to test the sql functionality.
Consolidation PR of #2678 and #2679 since the functions ended up being
much more complicated than I initially thought and had to be done in a
single PR.
Closes#2757
