you want an event for every single proposer preference? not like an array of everything that was sent?

guess we can go with this for now and change it if it's too noisy

Supersedes #593 with ethereum/consensus-specs#5196, ethereum/consensus-specs#5236 added Adds the proposer preferences API for Gloas, deprecates the legacy fee-recipient/gas-limit endpoints, and tightens `beacon_committee_subscriptions` for CGC bookkeeping. ## Added - `POST /eth/v1/validator/proposer_preferences` — VC submission of signed preferences and publishes them on the `proposer_preferences` gossipsub topic. - `proposer_preferences` SSE event for messages passing gossip validation. - `Gloas.ProposerPreferences` / `Gloas.SignedProposerPreferences` types, including `dependent_root` (used for gossip dedup and validation). ## Deprecated - `POST /eth/v1/validator/prepare_beacon_proposer` — superseded by signed proposer preferences. Pre-Gloas support is REQUIRED; post-Gloas the endpoint MAY be a no-op or removed. - `POST /eth/v1/validator/register_validator` — fee recipient and gas limit move to signed proposer preferences. Same pre/post-Gloas support rules apply. ## Updated - `POST /eth/v1/validator/beacon_committee_subscriptions` — from Gloas onwards, BNs use the subscription set to identify which validators are using the node and to size the node's custody group count (CGC). VCs SHOULD submit one entry per attached active validator per attestation duty, including when multiple validators share the same `(slot, committee_index)`, so the BN tracks every attached validator rather than only one per subnet.
