This module extends ShareManager and ERC20Upgradeable, making vault shares externally transferable and fully compliant with the ERC20 standard.
It is intended for vaults that require tokenized shares usable across external protocols, wallets, or DeFi integrations.
Core share logic (minting, burning, whitelisting, lockups) is delegated to the inherited ShareManager, preserving consistent permission enforcement.
Whitelist enforcement, lockup mechanics, and share claim logic are integrated into the overridden _update hook, which ensures all token transfers pass necessary checks and call claimShares for non-zero actors.
Suitable for use cases where share liquidity, composability, or token standard compatibility (for example ERC20 or ERC4626 wrappers) is required.
