Add AI explain and recompose branch actions to Branch Views

Introduces AI-powered branch actions ("Recompose" and "Explain") directly into the branches view, enabling context menu options when branches are recomposable or have unpushed commits. Refactors and centralizes branch recomposability detection to ensure consistent logic across graph and views, improving maintainability and user experience. Enhances discoverability and workflow integration for AI-assisted Git operations.
