fix: support CGO_ENABLED=0 cross-compilation for permissions module

Split CGo-dependent screen recording detection into build-tagged
files: screen_recording_cgo.go (darwin+cgo) provides the real macOS
API call, screen_recording_other.go provides a no-op fallback for
cross-compilation in CI (CGO_ENABLED=0).
