fix(cli): append newline to text-mode emitResult so zsh PROMPT_SP doesn't erase the line

Browse source 
Headless text mode wrote `resultMessage.result` without a trailing newline.
In a TTY, zsh themes that use PROMPT_SP (powerlevel10k, agnoster, …) detect
the missing `\n` and emit `\r\033[K` before drawing the next prompt, which
wipes the final line off the screen. Pipe-captured output was unaffected,
so the bug only surfaced for interactive shell users — most visibly in the
background-agent flow where the drain-loop's final assistant message is
the *only* stdout write in text mode.

Append `\n` to both the success (stdout) and error (stderr) writes.
