Ankur SharmaandCopybara-Service d48679582d feat: Populate AppDetails to each Invocation
AppDetails require two pieces of information:
1) Instructions
2) Tools

Both these pieces of information are gathered using the llm_request that was passed to the model. This approach, slightly invasive, ensures that we capture the "exact" instructions and tools that were given to the model.
