feat: Add equals, hashCode, deep copy, and tests to MoonshotChatOptions
This commit enhances MoonshotChatOptions by: - Updating equals and hashCode methods for proper object comparison. - Updating copy() method, creating new instances of mutable collections (List, Set, Map, Metadata) to prevent shared state. - Adding MoonshotChatOptionsTests to verify copy(), builders, setters, and default values. Signed-off-by: Alexandros Pappas <[email protected]>
