television 0.15.6

//! Tests for CLI selection behavior: --select-1, --take-1, --take-1-fast, and their conflicts.
//!
//! These tests verify Television's automatic selection behaviors that allow scripts and
//! automated workflows to get results without user interaction. They also ensure that
//! conflicting selection modes are properly detected and rejected.
