@libsql/client embedded replica leaks memory

Hi! There is a major memory leak when using embedded replicas (calling client.sync and then making any query on the client).
The reproduction repo is here with instructions.

Here is a screenshot of the Fly container memory (using sync)
At the 13:24:00 mark, the load test is executed. Memory continues to grow and flat lines after the test ends (most of the memory is never released).
NOTE: and 2nd container was created (13:27:00) b/c the 1st almost ran out of memory

Here is a screenshot of the same app but w/o using embedded replicas:
At the 13:53:00 mark, the load test is executed. Memory never explodes and stays leveled. At the end of the test, the memory is freed (there's a slight difference from the start/end, but that's just normal node GC behavior... sometimes the ending memory is less than the starting memory)

Start with the linked turso_leak reproduction and follow its instructions to run client.sync followed by queries against the embedded replica. Compare memory during and after the load test with the non-embedded setup; done means identifying and resolving the leak so memory no longer grows persistently after the test.
