hunch 2.0.2

//! Integration tests for #46: WRONG_TYPE audit fixes.
//!
//! Tests three layers of fix:
//! 1. Structural: CJK episode markers (第N話/第N集) — pattern recognition
//! 2. Vocabulary: Anime bonus tokens (NCOP/NCED/PV/CM) → EpisodeDetails → Extra
//! 3. Architectural: Path-based type inference (tv/ → episode)
