• Added a JsonConstructor to CompositionSettings to handle initialization of nested properties during deserialization
• Simplified the default CompositionSettings creation in FusionComposeCommand by removing redundant explicit initialization
• Added logging for source schema download operations in FusionPublishCommand

File	Description
src/Nitro/CommandLine/src/CommandLine/Settings/CompositionSettings.cs	Added JsonConstructor to ensure all nested properties (Preprocessor, Merger, Satisfiability) are initialized with non-null default instances during deserialization, even when properties are missing from older JSON formats
src/Nitro/CommandLine/src/CommandLine/Commands/Fusion/FusionComposeCommand.cs	Simplified GetCompositionSettingsAsync by removing redundant explicit initialization of EnableGlobalObjectIdentification, relying instead on the new constructor defaults
src/Nitro/CommandLine/src/CommandLine/Commands/Fusion/FusionPublishCommand.cs	Added informative logging when downloading source schema versions to improve user feedback during publish operations
