Update z3ed CLI tool and project build configuration

- Updated `.clang-tidy` and `.clangd` configurations for improved code quality checks and diagnostics.
- Added new submodules for JSON and HTTP libraries to support future features.
- Refined README and documentation files to standardize naming conventions and improve clarity.
- Introduced a new command palette in the CLI for easier command access and execution.
- Implemented various CLI handlers for managing ROM, sprites, palettes, and dungeon functionalities.
- Enhanced the TUI components for better user interaction and command execution.
- Added AI service integration for generating commands based on user prompts, expanding the CLI's capabilities.
