Replaces the hash-preimage envelopes with a Groth16 shielded pool.

zk/: circom circuit (Poseidon Merkle membership, depth 10, recipient bound to the proof), single-contributor setup script and its output, client library

Love.deposit(bytes32 commitment) locks a fixed 0.01 wETH; Love.claim(proof, root, nullifierHash, recipient) pays its LOVE to recipient

the plain deposit(uint256) and withdraw are unchanged

tests run against real proofs
