fix: catch UiPathBaseRuntimeError and add error category to I/O panel

cristipufu · claude · cristipufu · commit 64aabca28fc3 · 2026-02-16T17:31:32.000+02:00
LangGraphRuntimeError extends UiPathBaseRuntimeError (not UiPathRuntimeError),
so errors like GraphRecursionError fell through to the generic Exception handler
which used code="Unknown". Now catches the base class and surfaces the structured
code, title, detail, and category in the error panel.
