refactor: unify node types into a single PromptTemplate model

- Removed individual node components (SlashCommandNode, FileOperationNode, etc.) and replaced them with a unified PromptTemplateNode.
- Updated flow types and interfaces to reflect the new single node type system.
- Refactored flow execution logic to handle the new unified model, simplifying node execution and context handling.
- Adjusted UI components to support the new PromptTemplateNode, including instruction display and context references.
- Cleaned up legacy code related to removed node types and ensured compatibility with the new structure.
