Update .gitignore and remove obsolete documentation files

- Added new entries to .gitignore for build artifacts and macOS output directories to streamline the build process.
- Deleted outdated documentation files: AUTH_LOGIN_FIX.md, AUTBOOT_CONFIGURATION.md, BACKEND_FIXES.md, BACKEND_STARTUP_FIX.md, BITCOIN_CORE_HEADLESS_FIX.md, BITCOIN_CORE_UI_COMPLETE.md, BITCOIN_STANDALONE_UI_COMPLETE.md, BITCOIN_UI_COMPLETE.md, BOOT_SEQUENCE_DIAGRAM.txt, and BUILD_COMMANDS_REFERENCE.txt to declutter the repository and remove unnecessary content.

 ## Overview
 
-Archipelago is a next-generation Bitcoin Node OS built on Alpine Linux with Podman containerization, combining the modularity of Parmanode with the security and efficiency of a minimal server OS.
+Archipelago is a next-generation Bitcoin Node OS built on Debian Linux with Podman containerization, combining the modularity of Parmanode with the security and reliability of a proven server OS. Similar to StartOS, we use Debian Live for reliable USB boot and installation.
