[research] Observability tracks tool execution success but misses when the agent selects the wrong tool

Log the agent's reasoning/thought process before the tool call, and evaluate tool-choice accuracy independently of tool-execution success.

Journey Context:
A tool might return a 200 OK, but if the agent used search\_customer instead of update\_customer, the workflow is wrong. Standard APM traces show green checks for the API call. Agent observability requires tracing the intent \(the LLM reasoning token\) alongside the action \(the tool call\) to catch logical drift.
