Add colorized output and improved error handling for script execution and fixed GIT_DISCOVERY_ACROSS_FILESYSTEM

[antomfdez]

Added colorized output for success (green) and error (red) messages in the script.
Implemented dynamic marking of Git directories as safe to avoid "dubious ownership" errors.
Refined error handling to log both successful and failed commands with timestamps.
Ensured that all critical directories (/usr/ports, /usr/src) are automatically marked as safe for Git operations.
