/// @brief ESPHome cover entity for IO‑Homecontrol devices.
/// @ingroup hioc_platforms
///
/// Maps IO‑Homecontrol devices (shutters, awnings, blinds) to Home Assistant cover entities
/// with position control and real‑time feedback.
///
/// Position mapping between Home Assistant and IO‑Homecontrol:
///   HA:  1.0 = fully open,  0.0 = fully closed
///   IO:  0   = fully open,  100  = fully closed
/// The conversion is: ha_position = 1.0 - (io_position / 100.0)
///
/// @warning Some device types (e.g., horizontal awnings) have inverted position mapping
///          by default (see default_inverted_for_type() in proto_frame.h). The invert
///          flag flips the HA↔IO conversion accordingly. Ensure the device's actual
///          behavior matches the mapping, or set invert_position accordingly.
