* bug-fix(stage-ui): fixed the system prompt not successfully initialised bug
* bug-fix(stage-ui): if it's already initialised, then nothing needs to do in onMounted()
* [autofix.ci] apply automated fixes
* bug-fix(stage-ui): removed onMounted() logic, which is unnecessary
* fix: removed a blank vue playground page in the dev-tool. This should be left for the next PR maybe...
