Elmo Eclipse Gear

• Adds two complete armor sets (Elmo and Dark Elmo) plus matching swords registered under the mod id elmoeclipsegear for server-side use on 1.21.1.
• Armor pieces use diamond-tier durability and protection; Dark Elmo gear is fireproof to match its netherite theme.
• Full-set bonuses: Elmo grants Resistance V; Dark Elmo grants small boosts to strength, speed, resistance, haste, and regeneration. Bonuses refresh every second while the full set is worn.
• Weapons: Elmo Sword is diamond-tier with standard sword reach and speed; Dark Elmo Sword is netherite-tier with a slightly quicker swing and fireproofing.
• Simple themed icons and armor layer textures are included for both sets so the items render with distinct red and deep eclipse styling.
• Known limitations/suggestions: no crafting recipes or loot integration yet; tweak effect balance or add progression/advancement hooks as desired.
