Bug: Vite/Babel Compilation Error - Duplicate declaration "TournamentMode"

## Description

The application fails to start and throws a compilation error (`Internal server error`) due to a duplicate declaration. This issue prevents the Vite development server from running correctly, effectively **blocking all local development** and testing for new features (like the planned animations).

## Error Log

```
3:59:47 PM [vite] (client) Pre-transform error: Duplicate declaration "TournamentMode"
12 | type TournamentView = 'settings' | 'bracket' | 'match' | 'stats';
13 |
> 14 | export const TournamentMode = () => {
| ^^^^^^^^^^^^^^
15 | const [currentView, setCurrentView] = useState('settings');
16 | const [tournament, setTournament] = useState(null);
17 | const [currentMatch, setCurrentMatch] = useState(null);
Plugin: vite:react-babel
File: /home/adrdev/Documents/github/hacktoberfest/tic-tac-toe/src/components/TournamentMode.tsx
```

## Root Cause Analysis

The error indicates that the component/variable **`TournamentMode`** is being declared more than once in the scope of the file `src/components/TournamentMode.tsx`.

This is a syntax error that Babel/Vite cannot automatically resolve.

## Proposed Solution / Fix

1. Inspect the file `src/components/TournamentMode.tsx`.
2. Locate and remove the redundant or duplicate declaration of the `TournamentMode` component, leaving only one correct export definition (likely the one starting on Line 14).
