Colored terminal output

[Muhtasim-Rasheed]

Summary

Crust currently prints everything in plain white text. It would be awesome if:

• Errors and important messages were color-coded.
• Users could print colored output too.

What to do

• Add the colored crate to the project.
• Use it to:
  • Color error messages (e.g. .red())
  • Color success messages (e.g. .green())
• Bonus: Add a user-facing function or flag to let them print colored text.

Difficulty

Beginner-friendly! Minimal changes and very visual.
