- Add Config dataclass with get_config()/set_config() for injection - Add Config.from_args() for CLI argument parsing (testable) - Add platform font path detection (Darwin/Linux) - Bound translate cache with @lru_cache(maxsize=500) - Add fixtures for external dependencies (network, feeds, config) - Add 15 tests for Config class, from_args, and platform detection This enables testability by: - Allowing config injection instead of global mutable state - Supporting custom argv in from_args() for testing - Providing reusable fixtures for mocking network/filesystem - Preventing unbounded memory growth in translation cache Fixes: _arg_value/_arg_int not accepting custom argv
