feat(cli): show PID

[hdcodedev]

Context

Add PID visibility for CLI command output so users can see the running process ID.

Implementation

• Parse and persist pid from commandExecutionStatus updates in the CLI state layer.
• Include pid in synthetic command_output asks and subsequent updates so the UI can render it.

How to Test

• Run the CLI and execute a command that produces a command_output ask.
• Confirm the ask shows PID: <number> while the command is running.
• Let the command complete and verify the PID remains visible in the final output message.
