Implements the Hungarian algorithm for optimal assignment between two sets of matchers (e.g., methods vs. method matchers). This is a generic bipartite matching utility that can be extracted and reused in any project requiring unordered set matching with cardinality constraints. The implementation is self-contained, operating on iterable ranges and a cost function, and does not depend on DexKit-specific types.

A trie data structure for fast hierarchical string matching, used to filter classes by package inclusion/exclusion. It supports insertion of patterns (e.g., 'com.example.**') and lookup of longest prefix or exact match. The interface is clean and could be reused as a standalone package filter or general-purpose prefix tree for any domain (e.g., URL routing, name filtering).

Provides a generic JVM caching store with generation-based invalidation, single-flight load deduplication, and support for single, list, and map result types. It handles concurrent access with `AtomicInteger` and `ConcurrentHashMap`, and includes partial batch write protection and corruption recovery. This pattern is reusable for any application needing a lightweight, consistent cache layer that can be backed by different stores (e.g., memory, SharedPreferences).
