/**
* Enhanced scoring function for bounty relevance.
* Logic:
* 1. Reward Weight (40%): Logarithmic scaling ensures higher rewards are prioritized without
* overshadowing small tasks. log2(reward) * 5.
* 2. Funding Status (30%): Higher funding percentage increases confidence. fundedPercent / 5.
* 3. Recency (20%): Newer bounties need more exposure. Linear decay over 30 days. max(0, 30 - postedDaysAgo) / 2.
* 4. Activity/Trending (10%): Shows community validation. claimedCount * 2.
