fix(coding-agent): suppressed circular plan-yolo notice

Passed explicit plan-yolo state into print mode so the startup-default warning only describes bare headless runs.

Fixes #8312

+### Fixed

+- Fixed print mode claiming `plan.defaultOnStartup` was ignored and recommending `--plan-yolo` when that headless plan flow was already active ([#8312](https://github.com/can1357/oh-my-pi/issues/8312)).
