Add support for displaying nested agent calls (agent -> subagent -> subagent) with proper indentation and visual indicators. The UI now shows delegated calls in a collapsible section with: - Indented display for each nesting level - Colored borders to indicate hierarchy depth - Level indicators showing nesting depth - Protection against excessive nesting (max 10 levels) Includes comprehensive test coverage for nested call scenarios. Fixes kagent-dev#972 Signed-off-by: Naveen Alok <[email protected]>

Could you add a couple of screenshots to the PR? (I'll try to test it out tomorrow, but I am curious to see how it looks like :)) |
|
I think there might be some issues with how this works -- I've created a nested agent that references k8s, istio and helm agents - and the nested display looks incorrect. 
so it shows the k8s-agent being called which is correct, but then it shows k8s-agent twice as nested calls and then again at the top level (and nested again) with same inputs.
