Adam Perry @ OpenAI 6fa3bcaae8 Add exec-server RPC timing and process startup tracing (#47680)
## Why

Detached work can keep request spans open beyond response enqueueing. Record explicit phase timings to distinguish request handling from the full span lifetime.

## What changed

- Record server dispatch and response enqueue offsets from request receipt, plus a response enqueue event for HTTP responses that bypass the dispatcher.
- Emit client request enqueue and response receipt events, including success or server-error outcomes and reader-to-caller delay. Carry completion timestamps to the awaiting task so receipt events retain its tracing context.
- Add spans for process startup, sandbox preparation, shell snapshot preparation and capture, and process spawning. Record process identifiers only when nonempty and at most 64 bytes long.
