Add merkle proof verification functionality in Noir: - merkle_check function to verify proofs and compute root - Support for generic hash functions via HashFn type - Comprehensive tests for even, odd, and power-of-2 leaf counts - Uses Keccak256 for testing (matching Rust reference implementation) The function iterates through proof nodes and applies hashing based on node side (LEFT/RIGHT) to reconstruct the Merkle root from a leaf.
Rename the function to merkle_proof_check for consistency with existing documentation and examples. Add comprehensive documentation: - Rename function from merkle_check to merkle_proof_check - Update all tests to use new function name - Add new example showing low-level API usage - Update README to list new example This ensures consistency across the codebase and makes the function name match what's already documented in README and used in examples.
