Under the hood

Internal CLI option and error classes were renamed with no change in behavior

What

Internally, the class used to build print-mode CLI flags such as --permission-prompt-tool, --system-prompt, and --plan-mode-instructions was renamed, and the class used for invalid-choice errors on those options was also renamed.

Why

This is a naming-only change with no effect on how these flags behave or appear to users.
