Module token 

Hopper-native SPL Token CPI builders.

The API is Hopper-owned (builder pattern over AccountView / Signer) and execution flows through Hopper’s checked native CPI semantics.

Provides checked-by-default TransferChecked, MintToChecked, BurnChecked, ApproveChecked, CloseAccount, Revoke, SetAuthority, FreezeAccount, ThawAccount, SyncNative, and InitializeAccount builders. Multisig owner flows are first-class via bounded signer-account slices. Deprecated plain Transfer/MintTo/Burn/Approve builders are compiled only when legacy-token-instructions is explicitly enabled.
