Daily/weekly challenges#8

It could be fun to have more ways to experience and practice Catan outside of normal games.

Possible formats:

• Puzzle-style challenges: players must make the right sequence of moves to solve a scenario or win
• Side-goal challenges: players try to complete specific objectives in a match, not just win

Examples:

• Build at least 3 cities
• Win without using more than 5 development cards
• Reach a target resource or settlement milestone
• Complete a scenario under certain constraints
