What's Changed

CAP-71 — Auth delegation for custom accounts — Adds support for delegating a custom account's __check_auth to another address. CustomAccount::delegate_auth hands authorization to a G- or C-address that performs the actual authentication logic, and CustomAccount::get_delegated_signers returns the delegated signers supplied in the transaction's authorization payload for verification. (#1896)

Zero-copy BytesN::from for [u8; N] — BytesN::from now uses BytesN::to_array instead of allocating, avoiding extra memory allocation and significantly reducing CPU cost on conversions (up to ~80% on larger arrays in end-to-end benchmarks). (#1888)
