Extends ContentRepository with optional cacheDir: cached packs in <cacheDir>/seasons/*/pack.json merge with bundled ones (cached wins for same id), corrupt/future-schema packs silently ignored, refresh() fires ContentDownloader.sync() once per session. main() wires the real cache+downloader instance; default constructor stays bundled-only for tests.
