📸 fix: Snapshot Options to Prevent Mid-Await Client Disposal Crash (#12398)
* 🐛 fix: Prevent crash when token balance exhaustion races with client disposal

Add null guard in saveMessageToDatabase to handle the case where
disposeClient nullifies this.options while a userMessagePromise is
still pending from a prior async save operation.

* 🐛 fix: Snapshot this.options to prevent mid-await disposal crash

The original guard at function entry was insufficient — this.options is
always valid at entry. The crash occurs after the first await
(db.saveMessage) when disposeClient nullifies client.options while the
promise is suspended.

Fix: capture this.options into a local const before any await. The local
reference is immune to client.options = null set by disposeClient.

Also add .catch on userMessagePromise in sendMessage to prevent
unhandled rejections when checkBalance throws before the promise is
awaited, and add two regression tests.
