agent_graph.py broken due to missing await

[halfpasttense]

Async function build_graph is not awaited when called recursively for the sub agents. This breaks the graph rendering in the web UI.

for sub_agent in agent.sub_agents:
await build_graph(graph, sub_agent, highlight_pairs) # add missing await
draw_edge(agent.name, sub_agent.name)

Thanks @halfpasttense for catching this, do you want to send a PR for this? I think this is a good contributing point

@wyf7107 I would love to but I don't have a Contributor License Agreement and getting one signed would not be a simple process.

Duplicate of #927

@Jacksunwei This fix was undone almost immediately by another commit and so it's broken again...

[Jacksunwei]

OMG, you're right.

This commit
da4bc0e from a PR is the culprit.

@selcukgun could you help rollback the change in da4bc0e
