This change threads the newer complCaseSensitivity field through existing prompt-based APIs instead of maintaining separate primed variants that took an explicit case-sensitivity argument. In practice, DynamicProjects, WorkspaceDir, and Prompt.Directory now respect the setting already present in XPConfig, and several redundant ' helper functions were removed from the public surface. The result is a smaller, more consistent API with directory completion behavior controlled in one place. Practical effect: users configure case sensitivity once in XPConfig and prompts behave accordingly.
