Add an authored guide for synchronous tokenized-vault workflows and generated reference pages for every cast erc4626 subcommand. Keep the reference generator grouping the command family under Vault Commands.\n\nDocuments foundry-rs/foundry#16601.

Adds
cast erc4626(withcast vaultas an alias) for all sixteen ERC-4626-specific methods in the synchronous base interface. Read commands accept the usual RPC and block options, while deposit, mint, withdraw, and redeem use ABI-generated calldata and the sharedcast sendtransaction path so wallet, browser, and Tempo behavior stays aligned with the generic sender. The vault's inherited ERC-20 share operations remain available throughcast erc20.The command emits targeted compatibility guidance when a vault reports conservative zero deposit or mint maxima, when it reports a zero exit maximum for an owner that still has shares, and when
asset()returns the ERC-7535 native-asset sentinel. Failed preview calls also explain the intentional ERC-7540 asynchronous-vault behavior. End-to-end coverage executes every base selector against a local writable vault, uses a table-driven fixed-block Ethereum fork for Morpho MetaMorpho, Yearn V3, and Maple syrupUSDC, and runs the same complete read surface through a pinned Tempo mainnet fork of this Morpho-style vault.Follow-ups
Separate changes can add ERC-7540 request/claim flows and ERC-7575 multi-asset share discovery, first-class ERC-7535 native-value writes, slippage-bounded ERC-5143 or router-style operations, permit/approval composition, and a richer vault summary or position command with asset/share unit formatting. Keeping those extensions outside this PR leaves the initial surface exactly aligned with the broadly deployed synchronous ERC-4626 selectors.
