//! OTG USB Gadget unified management module
//!
//! This module provides unified management for USB Gadget functions:
//! - HID (Keyboard, Mouse)
//! - MSD (Mass Storage Device)
//!
//! Architecture:
//! ```text
//! OtgService (high-level coordination)
//!     └── OtgGadgetManager (gadget lifecycle)
//!             ├── EndpointAllocator (manages UDC endpoints)
//!             ├── HidFunction (keyboard, mouse_rel, mouse_abs)
//!             └── MsdFunction (mass storage)
//! ```
//!
//! The recommended way to use this module is through `OtgService`, which provides
//! a high-level interface for enabling/disabling HID and MSD functions independently.
//! Both `HidController` and `MsdController` should share the same `OtgService` instance.
