Add agent tool to report errors

[whoabuddy]

The agent does a good job of interpreting errors and relaying a message to the user, e.g.

We should have a tool available that allows an agent to report the error where it can fill out a templated report and it gets sent back to us. Makes it very fluid for people to ask the agent to "do something" about the error.

Taking that a step further, we could automate the error handling, since tools shouldn't really fail anyway.

If we standardize the new ToolResponse format across all tools then we can judge the difference between a failure (exception) and a failed tool request, e.g. there was no data.
