//! Deprecation warnings for truly redundant commands
//!
//! ## Design Philosophy (Hybrid CLI)
//! - Human-friendly commands (`dead`, `cycles`, `twins`, `health`, `audit`) are STABLE
//! - jq-style queries (`.dead_parrots`, `.cycles`) are for power-users/CI
//! - Only truly redundant aliases are deprecated:
//! - `zombie` → use `dead` (same output)
//! - `sniff` → use `loct findings` (same output)
//!
//! Removal of redundant commands planned for 0.9.0.
/// Print a deprecation warning to stderr (does not break piped output)
