Implement multiple game improvements

- Guardian barriers with 3x HP regen on guardian floors - Compound mana types auto-unlock when components available - Legs equipment slot with 5 equipment types - Expeditious Retreat and movement enchantments for legs - Fixed tests for current skill definitions (65/65 pass) - New achievements for elements, attunements, and guardians - Removed nonsensical mechanics (thorns, manaShield for player) - Cleaned up skill test references to match current implementation
