Add TraitSwap & LootBox template to Algorand ecosystem

[blockmaker-ai]

Adds the open-source TraitSwap & LootBox template to the Algorand ecosystem.

• Repo: https://github.com/filippofalleroni/Trait-swap-and-Loot-Box
• A reusable, open-source template for Algorand NFT projects: an ARC-19 trait swapper plus a verifiably-random (block-seed/VRF) loot box, with a commit-reveal smart contract.
• Production-tested: powers the live trait lab and loot box at https://monstrs.famverse.xyz

Hi maintainers — friendly nudge on this one. It's a single repadd to the Algorand ecosystem (TraitSwap & LootBox template) and the validation check is passing. Would appreciate a review when you have a moment, as it's referenced in an active funding proposal. Thanks!
