This package is for serverless access to the Turso Cloud using SQL over
HTTP protocol. The purpose of this package is to provide the same
interface as `@tursodatabase/turso`, but for serverless environments
that cannot host the database engine.
The package also provides a `@libsql/client` compatibility layer in the
`@tursodatabase/serverless/compat` module for drop-in replacement for
existing clients.

- enable indexes, otherwise it doesnt work at all
- rename limbo to tursodb
- use mode=list instead of mode=pretty for less bulky tursodb results

Closes#2201
- When an interior index cell is replaced, it can cause the page where
the
replacement happens to overflow OR underflow. On `main` we did not check
this case, because
the interior cell replacement always moves the cursor to a leaf, and if
the leaf
doesn't underflow, then no further balancing happens.
- The solution is to ALWAYS check whether the interior page where the
replacement
happens is underflowing OR overflowing, and balance that page regardless
of whether
the leaf page where the replacement was taken underflows or not.
So summary:
- InteriorCellReplacement: cell deleted from Interior page I,
replacement cell taken from Leaf L
and inserted back to Interior page I.
- If Leaf L underflows:
* balance it first
* then balance I if it overflows OR underflows
- If Leaf L does NOT underflow:
* balance I anyway if it overflows OR underflows

Closes#2150
Using `unwrap_or_default` can make `page_size` become 0 in this case,
which can lead to subtracting with overflow in `payload_threshold_max`
in case we have some sort of error. Better to unwrap the error here, as
in release mode we may not have overflow checks enabled to catch this.

Turns out #2192 was just me implementing a test wrong -- `BEGIN` is ofc
an alias for `BEGIN DEFERRED` so just executing `BEGIN` won't start a tx
yet. In short: `tursodb` does what you'd expect under snapshot
isolation, at least in this specific instance.
In any case, let's not waste the test -- I've now unignored it and fixed
it.
Closes#2196
Currently, each record header is decoded at least twice: once to
determine the record size within the read buffer (in order to construct
the `ImmutableRecord` instance), and again later when decoding the
record for comparison. This redundant decoding can have a noticeable
negative impact on performance when records are wide (eg. contain
multiple columns).
This update modifies the (de)serialization format for sorted chunk files
by prepending a record size varint to each record payload. As a result,
only a single varint needs to be decoded to determine the record size,
eliminating the need to decode the full record header during reads.
Closes#2176
Small README cleanup:
1. Updated the contribution guide and license link to point to the local
CONTRIBUTING.md and LICENSE.md file instead of GitHub’s default page.
2. Linked each language in the bindings list to its respective
subdirectory for easier navigation.
