Feat/reputation score

Description

Reputation Score

What changed

types.rs

• Added DataKey::Reputation(Address) for persistent score storage.

profile.rs

• Added pub(crate) fn increment_reputation(env, user) — a plain Rust function outside #[contractimpl], so it is never exposed in the contract ABI and cannot be called externally.
• Added pub fn get_reputation(env, user) -> u64 — public read, defaults to 0.

giveaway.rs

• distribute_prize calls ProfileContract::increment_reputation after marking the giveaway Completed, incrementing the creator's score by 1.

test.rs

• test_reputation_starts_at_zero — new address has score 0.
• test_reputation_increments_after_distribute_prize — score is 1 after a full giveaway cycle.
• test_reputation_accumulates_across_giveaways — score is 2 after two completed giveaways.

Security note

increment_reputation is pub(crate) and lives outside #[contractimpl]. The Soroban macro only generates ABI entries for functions inside that block, so there is no on-chain entry point for it. The only code path that can call it is distribute_prize within the same crate.
