Background

What does this PR do?

Implements three key methods in the ReservoirService for NFT collections:

• getOwnedNFTs: Fetch NFTs owned by a specific address

My changes require a change to the project documentation.

• Update README.md for plugin-nft-collections
• Add method descriptions in code comments

Testing

Where should a reviewer start?

• Review packages/plugin-nft-collections/src/services/reservoir.ts
• Focus on the newly implemented methods

Detailed testing steps

1. Unit Tests

   • Verify getOwnedNFTs returns correct NFT data structure
   • Test createListing with various input parameters
   • Validate getFloorListings sorting and filtering

2. Integration Tests

   • Test methods with real Reservoir API credentials
   • Verify error handling mechanisms
   • Check performance monitoring functionality

3. Manual Verification

   • Test each method with sample collection and token addresses
   • Validate marketplace URL generation
   • Confirm error logging works as expected

Additional Notes

• Implemented with comprehensive error handling
• Added performance monitoring for API calls
• Follows existing service interface and design patterns
