grantOpenPrivacySettings

Opens System Settings' Privacy & Security → Camera pane via the documented x-apple.systempreferences: URL scheme — the real, Apple-sanctioned mechanism macOS provides for this (unlike the browser target, which has no equivalent at all; see PlatformGrantDelegate.web.kt). Only grant-desktop can call this: it needs NSWorkspace (AppKit), which grant-core's jvmMain deliberately does not depend on, since that module also has to compile on any JVM, not just macOS.

Not permission-specific by URL — com.apple.preference.security?Privacy_Camera deep-links to the Camera row specifically, but the same mechanism covers every Privacy_* anchor (Microphone, Contacts, Calendars, ...). One exported function, not one per permission.
