feat(client): add TCP request queue for safe concurrency
...
The previous implementation allowed multiple concurrent async calls
(query, execute, ping) to interleave writes on the same socket,
which corrupted the binary protocol framing when NodeBB fired
parallel database operations.
Add an internal _requestQueue and _requestLock so that all TCP
requests are serialized: each async operation enqueues a task,
and tasks are drained one at a time via setImmediate().
