Adds the on-chain mechanism assumed by docs/notes/add-privacy-to-love.md, folded into Love.sol:

deposit(bytes32 secretHash, uint256 wethAmount) — overload of the existing deposit, pulls wETH and mints LOVE the same way, but locks it into a secret-locked envelope (auto-incrementing depositId, decrementing remaining) instead of crediting the caller. Keeps the peg invariant (totalSupply() == WETH.balanceOf(this) * RATE) exactly.

claim(uint256 depositId, bytes32 secret, uint256 loveAmount) — new function, bearer-note semantics: whoever proves the secret is paid, reusable across partial claims.

withdraw is untouched — a claimed balance redeems for wETH the normal way.

Tests in test/LoveEnvelope.t.sol cover deposit/claim accounting, independent envelopes, wrong-secret/unknown-deposit/insufficient-remaining reverts, and fuzzing.
