Adds the ssv-spec wire constants for the new ePBS (Gloas) duties, per SIP #94.

What

Domains (beacon_types.go): DomainBeaconBuilder (0x0B), DomainPTCAttester (0x0C), DomainProposerPreferences (0x0D) — the consensus-spec Gloas domains.
Roles: beacon roles BNRolePTCAttester / BNRoleProposerPreferences / BNRoleEnvelopeBuilder and matching runner roles RolePTCAttester / RoleProposerPreferences / RoleEnvelopeBuilder (7/8/9), wired through MapDutyToRunnerRole and both String() methods.
Partial-sig types: PTCAttesterPartialSig (7), ProposerPreferencesPartialSig (8). (§6 envelope post-consensus reuses PostConsensusPartialSig, discriminated by role, so it adds no type of its own.)

Why

Consumed by the node-side ePBS implementation (PTC attestation runner first). The remote signer (ekm) lives in a separate module that can only reference signing domains via ssv-spec, so the PTC signing path needs DomainPTCAttester here rather than node-side.

Branched off the commit ssv currently pins, so the downstream go.mod bump is purely additive.


          types: add ePBS (Gloas) domains, roles, and partial-sig types

d1675a2

Per SIP ssvlabs/SIPs#94, add the wire constants for the new ePBS duties:
- domains DomainBeaconBuilder (0x0B), DomainPTCAttester (0x0C),
  DomainProposerPreferences (0x0D)
- beacon + runner roles for PTC attester, proposer preferences, and envelope
  builder (7/8/9), wired through MapDutyToRunnerRole and the String() methods
- partial-sig types PTCAttesterPartialSig (7) and ProposerPreferencesPartialSig (8)

          ekm: support Gloas (ePBS) PTC payload-attestation signing

19feda3

Bump ssv-spec to the branch carrying the ePBS constants (ssvlabs/ssv-spec#632) and
add DomainPTCAttester signing:
- LocalKeyManager signs the payload-attestation root via the generic ssz.HashRoot
  signer (no slashing protection — PTC is not in the slashing predicate).
- RemoteKeyManager returns an explicit "not supported" error, since Web3Signer has
  no payload-attestation request type.

Also realign a test for the ssv-spec testingutils change (TestingPhase0AggregateAndProof
is now a constructor).

          gloas: add PTC attester runner on ssv-spec ePBS constants

4ce1289

Adopt the ePBS roles/domains/partial-sig types now in ssv-spec (ssvlabs/ssv-spec#632)
and add the PTC attestation runner (SIP #94 §3):
- bump ssv-spec to the branch carrying the constants
- collapse the node-side gloas placeholders onto spectypes.* (roles, domains,
  partial-sig types, and the now-redundant beacon->runner role mapping, which
  ssv-spec's MapDutyToRunnerRole handles); gloas keeps only the wire types
- add PTCAttesterRunner: a no-consensus partial-signature runner that freezes its
  beacon node's PayloadAttestationData observation, signs it under DomainPTCAttester,
  and reconstructs + submits one PayloadAttestationMessage per validator once a
  threshold of operators converge on byte-identical data

Just quick small nit. I did a find all for BNRoleEnvelopeBuilder according to the PR description but found nothing. In the code it actually is BNRoleEnvelopeProposer

          types: add the builder request-auth domain and partial-sig type

ac6b423

DomainRequestAuth pins builder-specs' DOMAIN_REQUEST_AUTH (0x0b000001), the
application-namespace domain authenticating direct validator-to-builder
requests under Gloas (ePBS) — genesis-style compute_domain, never
fork-versioned, and not to be confused with the beacon DomainBeaconBuilder
(0x0b000000). RequestAuthPartialSig(9) is the partial-signature type its
threshold signing rides on: an SIP-94 §5 extension carried under
RoleProposerPreferences (ssvlabs/ssv#2962).
