Pull request overview

This PR extends the Nitro CLI/client to read Fusion composition settings stored on a stage in Nitro and apply them during fusion publish, ensuring stage-level composition configuration can override (or fall back to) archive-embedded settings.

Changes:

• Added GraphQL schema + persisted operation to fetch Stage.compositionSettings and exposed it via IFusionConfigurationClient.GetStageCompositionSettingsAsync.
• Updated Fusion publish flow to download stage composition settings and merge them into the effective composition settings used for composition.
• Added/updated CLI tests to validate merging semantics (null/partial stage settings) and error handling when downloading stage settings fails.
