🦡ERC-4626 Vault Architect

Pass the invariant fuzz suite to unlock a Soulbound NFT mint in Prüfstand.

Architecture Blueprint

Vault wraps underlying ERC-20 deposit asset, issuing fractional shares. Allocates capital to external yield strategies while strictly maintaining conversion invariance.

1. Caller ➔ [Entry Call] ➔ ZehnVault4626.sol

2. Execute protocol-defined state transition

3. Verify invariants hold post-transition
