Erik JohnstonandClaude Opus 5.5 1355f6c9f8 Send BEGIN with the first statement in the Rust sync store ...

The sync store's transactions (`SyncReader::begin` and `begin_write`),
which the Rust sync and sliding sync handlers and the persister's reader
use, still sent `BEGIN` on its own and waited for it.

As for `WriteTxn`, the `BEGIN` now goes out with the first statement:
with its execution when the connection has it cached, otherwise with its
prepare. If the `BEGIN` fails, the connection is discarded. A
transaction that runs nothing sends neither `BEGIN` nor `COMMIT`.
