docs(changeset): Added Referrer type to enssdk (raw 32-byte onchain referrer bytes). Runtime helpers (buildEncodedReferrer, decodeReferrer — renamed from decodeEncodedReferrer, ZERO_ENCODED_REFERRER, and related constants) moved from @ensnode/ensnode-sdk to @namehash/ens-referrals, which now owns a branded EncodedReferrer type returned by buildEncodedReferrer. buildEncodedReferrer now accepts Address (previously NormalizedAddress) and normalizes internally.

+Added `Referrer` type to `enssdk` (raw 32-byte onchain referrer bytes). Runtime helpers (`buildEncodedReferrer`, `decodeReferrer` — renamed from `decodeEncodedReferrer`, `ZERO_ENCODED_REFERRER`, and related constants) moved from `@ensnode/ensnode-sdk` to `@namehash/ens-referrals`, which now owns a branded `EncodedReferrer` type returned by `buildEncodedReferrer`. `buildEncodedReferrer` now accepts `Address` (previously `NormalizedAddress`) and normalizes internally.
