On the web, use
BEGIN EXCLUSIVEinstead of a regularBEGINwhen starting a write transaction. The motivation for this is:BEGINwill start as a read transaction and then upgrade to a write transaction when necessary. Since we're likely to issue writing statements inwriteTransaction, we can skip the read->write upgrade step.BUSYand then automatically retrying the SQLite call. There were some issues with this and the new Rust sync client. We will fix those in a core extension update, but obtaining a write transaction directly instead of inpowersync_controlcould still avoid some of those retries.
