cassirer-openai deede7201d Keep rollout trace terminal sessions distinct when process IDs are reused (#56011) ...

## Why

Runtime process handles are recyclable and thread-local. Using them as terminal session identities can merge separate commands or associate `write_stdin` operations with the wrong exec.

## What changed

- Give each exec a distinct terminal session and track the latest session for each thread-local process handle.
- Record the exec selected by `write_stdin` at runtime and use it to correct session membership during replay, including when dispatch is delayed until a handle is reused.
- Fall back to the latest session for the thread and handle when replaying older traces without runtime target events.

## Testing

Extend reducer coverage for process ID reuse across threads and successive execs, stdin session membership, and delayed runtime target resolution.
