Pull Request Overview

This PR fixes an issue where the command prompt was missing when switching between TTY screens. The fix ensures that when changing screens, a prompt is displayed if the cursor is at the beginning of a line, and prevents duplicate prompts from being printed.

• Added a call to tty_print_prompt() when switching TTY screens
• Modified tty_print_prompt() to only print the prompt when the cursor is at column 0

The logic is inverted. The prompt should be printed when curr_tty->column == 0 (at the start of a line), but the current condition returns early when not at column 0, which means the prompt will only be printed when the cursor is NOT at the beginning of the line.

Suggested change

	if (curr_tty->column != 0)
	return;
	if (curr_tty->column == 0)
	tty_putstr(TTY_PROMPT);
	}
