Michael Bolin 129ea2aaf5 Log multi-agent communication lifecycle (#30872)
## Why

[#30867](https://github.com/openai/codex/pull/30867) makes
`submit_inter_agent_communication` the common outbound sink for
multi-agent v2 communications. This follow-up uses that single point to
log every communication lifecycle without requiring new hooks as spawn,
messaging, follow-up, or result paths evolve.

For each communication, the logs need to identify its type, sender and
receiver threads, and content, while correlating the successful send
with receipt by the destination mailbox. The logging path must not query
externally supplied time providers because those calls can be expensive
for app-server clients.

## What changed

- Added structured `INFO` events on the OpenTelemetry-exported
`codex_otel.agent_communication` target for `spawn`, `message`,
`followup`, and `result` communications.
- Logged successful sends from `submit_inter_agent_communication` with
the communication kind, sender and receiver thread IDs, content, and
submission ID.
- Logged receives after the communication has been enqueued in the
receiver mailbox, using the same submission ID.
- Avoided time-provider calls and other asynchronous work in the logging
path.
- Narrowed ordinary spawn and send-input APIs to `Vec<UserInput>` so
`Op::InterAgentCommunication` cannot bypass the context-bearing
centralized path.

The refactor does not change submission IDs, capacity checks, last-task
bookkeeping, mailbox ordering, protocol types, rollout data, or
model-visible context.

## Event shape

Illustrative JSON representation of the two independently emitted
records:

```json
[
  {
    "event.name": "codex.agent_communication",
    "communication_id": "019f20e1-40d1-7890-a123-456789abcdef",
    "kind": "spawn",
    "state": "send",
    "sender_thread_id": "019f20df-fbe1-7890-a123-456789abcdef",
    "receiver_thread_id": "019f20e1-3f79-7890-a123-456789abcdef",
    "content": "inspect the repository"
  },
  {
    "event.name": "codex.agent_communication",
    "communication_id": "019f20e1-40d1-7890-a123-456789abcdef",
    "state": "receive"
  }
]
```

Consumers join the receive record to the send record by
`communication_id` for the immutable communication metadata.

## Testing

- Extended the existing end-to-end multi-agent v2 spawn test to verify
content, both thread IDs, and a correlated send/receive submission ID.
- Re-ran focused control and handler coverage for direct messages,
follow-up tasks, and completion results.
