Fixes #111: MerkleTree proof verification now validates that proof.siblings.length === proof.treeDepth. Changes: - Create MerkleTree module with from(), getProof(), verify() functions - verify() throws InvalidProofLengthError if proof length doesn't match expected tree depth - Add Proof.verifyWithDepth() to Zig for depth-validated verification - Comprehensive tests for proof length validation For a balanced tree with n leaves, depth = ceil(log2(n)). A proof with incorrect length is rejected. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
