[tool_crash] Unhandled RPCError (-32000) in ScreenshotCommand.runSkia when Impeller is enabled #196119
Description
Running flutter screenshot --type=skia against an app with Impeller enabled crashes flutter_tools with an unhandled vm_service.RPCError (RPCError at new _OutstandingRequest at package:vm_service/src/vm_service.dart-e893cf79).
The engine's _flutter.screenshotSkp service extension rejects SKP capture under Impeller with JSON-RPC error -32000 (Cannot capture SKP screenshot with Impeller enabled.). FlutterVmService._checkedCallServiceExtension rethrows non-disconnect RPCErrors, and ScreenshotCommand.runSkia (packages/flutter_tools/lib/src/commands/screenshot.dart) calls vmService.screenshotSkp() without catching vm_service.RPCError.
Error and stack trace:
_flutter.screenshotSkp: (-32000) Cannot capture SKP screenshot with Impeller enabled.

ScreenshotCommand.runSkia should catch vm_service.RPCError and call throwToolExit with the engine's error message.
