Implement tracking of outstanding LLM and Tool calls

This commit implements a listener pattern between ant.convo and the Agent for tracking outstanding calls.

* Added fields to the Agent struct to track outstanding LLM calls and Tool calls
* Implemented the listener methods to properly track and update these fields
* Added methods to retrieve the counts and names
* Updated the State struct in loophttp.go to expose this information
* Added a unit test to verify the tracking functionality
* Created UI components with lightbulb and wrench icons to display call status
* Added numerical indicators that always show when there are active calls
