Drop stale suspend/runtime-error events when debugger is no longer paused#356

…used DebugProtocolAdapter.emit defers dispatch via setTimeout(0). If isStopped flips back to false between queue and fire (e.g. auto-continue on entry breakpoint, rapid step), the suspend listener in BrightScriptDebugSession called setupSuspendedState -> getThreads, which threw "Cannot get threads: debugger is not paused" as an unhandled rejection. Re-check isAtDebuggerPrompt inside the deferred dispatch and drop the event if the debugger has already resumed. Fixes rokucommunity/vscode-brightscript-language#798

DebugProtocolAdapter.emitdefers every event withsetTimeout(0). When'suspend'is queued while paused,isStoppedcan flip back tofalsebefore the timer fires (auto-continue on entry breakpoint, rapid step, etc.). The deferred suspend listener inBrightScriptDebugSessionthen callssetupSuspendedState → getThreads, which throwsCannot get threads: debugger is not pausedas an unhandled rejection.Re-check
isAtDebuggerPromptinside the deferred dispatch and drop the event if the debugger has already resumed. Same guard applies to'runtime-error', which routes through the same handler path.Fixes rokucommunity/vscode-brightscript-language#798
