//! Top-level facade providing Go-style entry points for the QQ Bot Open API.
//!
//! These functions mirror the public surface of the official Go SDK so that
//! consumers used to that style can continue using the same names. The
//! framework itself is independent — these are simply convenience wrappers
//! around [`crate::api::BotApi`] and friends.
