Alex Kira fbe97c7929 Record tool registration metrics for each sampling request (#51868) ...

## What changed

Add the `codex.tools.registered` histogram to count finalized tool registrations by `exposure` and `tool_mode`, including zero counts for empty exposure categories. Record it once per sampling request before transport retries, excluding hosted tools. These counts describe the registered inventory, not model visibility or tool reachability.

## Testing

Add an integration test covering a stream retry, direct and deferred namespace tools, a model-only tool, and hosted web search. Verify that registrations are recorded once, hosted tools are excluded, and metric labels contain no tool names or descriptions.
