[3pts] Define ICombatStrategy interface and implement concrete strategies

[github-actions]

Description

Implement the Strategy pattern for combat actions using ICombatStrategy interface.

Depends on: Character base class issue

ICombatStrategy Interface

• Execute(Character attacker, Character target) returns CombatResult

CombatResult Class

• DamageDealt (int)
• AttackerName (string)
• TargetName (string)
• Message (string)

Concrete Strategy Implementations

MeleeStrategy

• Direct physical damage calculation
• Uses attacker's AttackPower and target's Defense

MagicStrategy

• Magic damage that partially bypasses defense
• Different calculation than melee

RangedStrategy

• Ranged attack with different mechanics
• Unique damage calculation

Integration

• Add CombatStrategy property to Character base class
• Include code comment explaining Strategy pattern choice

Acceptance Criteria

• ICombatStrategy interface defined with Execute method
• CombatResult class created with all properties
• MeleeStrategy implemented
• MagicStrategy implemented
• RangedStrategy implemented
• Character.CombatStrategy property added
• Each strategy has distinct damage calculation
• Code comment explaining Strategy pattern included
• All classes and interfaces documented with XML comments
