SkillPrompts - Release v1.1.0

• Added Prompt preview: Users can now preview the full prompt with variables before inserting it, ensuring they select the right one for their needs.
• Added Import/Export functionality: Users can now easily back up their prompt library or transfer it to another device by exporting and importing their prompts as JSON files.
• Added Favorites system: Users can now mark prompts as favorites for quick access, making it easier to find and use their most commonly used prompts.
• Add Reusable blocks: Users can now create reusable blocks of text or variables that can be easily inserted into multiple prompts, saving time and ensuring consistency across prompts. Unlike variables, blocks have fixed values that you manage. Use them to store common instructions, context, or any text snippets you want to reuse across multiple prompts.
• Fixed various bugs and added instructions for using variables / blocks.
