Feature Request: Allow bundles/applications to wire into the profile

[tacman]

In the same way that Symfony profiler bundle allows bundles to wire into the debug toolbar, it would be cool if this component allowed me to dispatch an event to my own section of the profile.

In particular, when I'm making agent calls I want to track my token count.

Just brainstorming here.

Yes, I think this is worth exploring. Right now the bundle is built around a single MetricsProviderInterface implementation, a fixed MetricsSnapshot, and a hard-coded dashboard renderer, so there is not yet a real extension point for third-party sections.

I would probably avoid a generic “dispatch an event during refresh” model as the first step, because refresh/render happens in the live update loop and should stay predictable. A custom metrics or custom section API feels easier to reason about and better suited to use cases like tracking agent token counts.
