//! Audio injection into an active call.
//!
//! Simply plays a file through the bridge's output so the target leg(s)
//! hear it (FileTrack → RTP).  The bridge's normal recording path
//! captures the conversation as usual — no special recorder handling
//! is needed.

/// Internally this sends [`MediaCommand::InjectAudio`] to the engine,
/// which uses the bridge's `replace_output_with_file` path — the same
/// mechanism as `Play` — for zero-copy file→RTP playback.
