Title: Add console-based Hangman game

This PR adds a classic command-line Hangman game.

Features

• Picks a random tech-related word for the user to guess.
• Grants the user 6 incorrect guesses (tries).
• Displays the hangman's ASCII art, remaining tries, letters already guessed, and the word with blanks (e.g., _ _ t h o _).
• Handles invalid input (non-letters, multiple letters) and repeated guesses.
• Reveals the word upon winning or losing and prompts the user to play again.
