- Implemented the `zap` command in the CLI to allow users to send sats to a user, event, or snippet using a NIP-60 wallet. - Created a new `zap.ts` file to handle the command logic and integrated it into the MCP server. - Added wallet balance command to check the balance of a user's wallet. - Enhanced the MCP server to register the new zap command and wallet balance command. - Introduced caching for wallets to optimize performance and reduce redundant network requests. - Updated database schema to include snippets table for storing code snippets. - Improved logging functionality for better debugging and tracking of operations. - Added functionality to save snippets to the database upon retrieval. - Updated project overview documentation to reflect new features and structure. - Refactored existing commands and logic for better modularity and maintainability.
