//! High-level install/upgrade helpers
//!
//! This module provides convenient wrappers that mirror ideviceinstaller's
//! behavior by uploading a package to `PublicStaging` via AFC and then
//! issuing `Install`/`Upgrade` commands through InstallationProxy.
//!
//! Notes:
//! - The package path used by InstallationProxy must be a path inside the
//!   AFC jail (e.g. `PublicStaging/<name>`)
//! - For `.ipa` files, we upload the whole file to `PublicStaging/<file_name>`
//! - For directories (developer bundles), we recursively mirror the directory
//!   into `PublicStaging/<dir_name>` and pass that directory path.
