Add a test/debug mechanism to shut down the OPFS async listener so that it can be inspected (it normally can't be because its tight event-listening loop ties up the thread) and then restarted.

Export sqlite3_trace_v2() to wasm and use it to ensure that the new per-VFS post-open SQL support in the DB ctor works. Default opfs vfs to journal_mode=truncate, as it's faster in that mode. Add 't' DB open-mode flag to enable SQL tracing to console.log().

OPFS VFS now lazily opens its sync access handle, as a step towards experimenting with relinquishing it during idle times to help avoid cross-tab and page-reload locking issues.

An alternative messaging strategy for the OPFS VFS proxy which uses only SharedArrayBuffer and Atomics, instead of worker messages, for communication (only the initial one-time handshake during initialization uses worker messages). It runs speedtest1 approx. 15-20% faster but still 20-ish% slower than WASMFS.

Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client. Rename x-sync-async.* to test-opfs-vfs.* Milestone: first successful test of OPFS without WASMFS.
