Adam Perry @ OpenAI eeae88d8a6 Add opt-in concurrent exec-server request dispatch (#36987) ...

## Why

Sequential dispatch lets a long-running request block unrelated health checks
and cleanup on the same connection.

## What changed

- Add `--concurrent-requests <COUNT>` for local and remote exec-server
  connections, while retaining sequential dispatch when the option is omitted
  or set to `1`.
- Preserve handshake ordering before enabling concurrent dispatch.
- Reserve separate capacity for status, signal, terminate, and close requests so
  they remain responsive when ordinary request capacity is saturated.
- Drain queued client responses during disconnect and cancel outstanding
  request tasks during connection shutdown.

## Testing

- Cover CLI parsing and concurrency-limit validation.
- Verify default sequential behavior, pipelined handshake ordering, concurrent
  request progress, control-request responsiveness, and disconnect handling.
