This commit enhances `AnthropicChatOptions` by: - Adding `equals` and `hashCode` methods for proper object comparison. - Implementing a deep `copy()` method, creating new instances of mutable collections (List, Set, Map, Metadata) to prevent shared state. - Adding `AnthropicChatOptionsTests` to verify `copy()`, builders, setters, and default values.
