Owen Lin 9ef08dcf2b Add multi-agent spawn latency and failure metrics (#47984) ...

## What changed

- Record successful spawn phase durations in `codex.multi_agent.spawn.phase.duration_ms`, covering residency reservation and fork context when applicable, child creation, durability waits, input admission, and total latency.
- Count spawn failures from the V1 and V2 tool handlers in `codex.multi_agent.spawn.failure`, grouped by bounded error categories.
- Use bounded labels for fork mode, multi-agent version, product SKU, and successful-spawn history mode. Emit phase timings only after a successful spawn.

## Testing

Add in-memory metrics tests for phase durations and labels, plus a tool-handler test verifying that a thread-limit failure emits one counter increment with the expected labels.
