chore(go.sum): synchronize checksum file with updated dependencies in go.mod

…0324190457-8f361e342cb9 to obtain the latest fixes and improvements

Replaces the pk910 replace directive with a direct dependency on
github.com/ethpandaops/go-eth2-client v0.0.1, and updates all imports
from github.com/attestantio/go-eth2-client to the ethpandaops fork.

Also adds spec.DataVersionHeze to ForkOrder (now exposed by v0.0.1).

refactor(metrics): replace hard-coded label strings with constants to reduce duplication and minimize errors

feat: ePBS SSE subs

* master:
  chore: swap go-eth2-client to ethpandaops fork v0.1.2 (#72)

…rator-supplied beacon node config URLs for clarity and maintainability

Bumps the go-ethereum pin from bal-devnet-3 commit 8f361e342cb9 (2026-03-23)
to bal-devnet-6 HEAD 73944e329925 (2026-05-07) — the EL branch deployed on
glamsterdam-devnet-3 per ethpandaops/glamsterdam-devnets ansible inventory.

bal-devnet-6 contains the latest BAL (EIP-7928) refinements plus Amsterdam
slot-number support (EIP-7843) needed for Gloas observability.

* master:
  publish typed fast_confirmation events
  recognize fast_confirmation event topic

* master:
  chore(deps): bump the actions group across 1 directory with 4 updates
  chore: add .gitignore file to exclude unnecessary files from version control
  refactor(metrics): replace hardcoded metric label strings with constants for better maintainability chore(api): remove inline comment suppressing gosec linter warning for consistency in code formatting
  chore(workflows): update golangci-lint version from 2.10.1 to 2.12.2 for improved linting functionality chore(workflows): change go-version from fixed version to version-file for better dependency management chore(go.mod): update Go version from 1.25.1 to 1.26.1 to align with current standards chore(go.sum): update dependency hashes after changing Go version and golangci-lint version

* master:
  style(tests): remove unnecessary empty lines in test files for better readability and consistency
  refactor: replace map[string]interface{} type with map[string]any for improved type safety in function signatures refactor: update for-loops to use range for better readability in tests and when iterating refactor: simplify sleep duration calculation by using a min function for clarity in logic refactor: utilize slices.Contains for checking topic existence in EventTopics refactor: replace interface{} with any in JSON unmarshalling for better type clarity in duration handling refactor: enhance goroutine handling in tests by adopting range in loops to improve readability

The EIP-7732 execution_payload and execution_payload_gossip SSE events carry a
flat payload summary, not a full SignedExecutionPayloadEnvelope. go-eth2-client
now decodes them into api/v1.ExecutionPayloadEvent; route that type through the
broker instead of the envelope so the handlers actually fire (previously every
event failed to type-assert and was dropped).

Bumps go-eth2-client to the flat-event build.

feat: deliver flat execution_payload / _gossip events

Wires the gloas head_v2 SSE topic through the standard path (topic
constant, dispatch, broker publish, OnHeadV2 subscriber, Node interface)
and bumps go-eth2-client to the build that parses the event. The topic
stays out of the default subscription list like the other gloas topics —
consumers opt in via their topic override.

feat: subscribe to and deliver head_v2 events

Adds RawExecutionPayloadEnvelope to the consensus API client and
FetchRawExecutionPayloadEnvelope to the Node interface, exposing
GET /eth/v1/beacon/execution_payload_envelopes/{block_id} (gloas onwards)
in JSON or SSZ depending on the requested content type.

feat: fetch raw signed execution payload envelopes

feat(beacon): add streaming raw API responses

This reverts commit 9f32aa9, reversing
changes made to b274ec0.

Relands the raw-streaming work from #81: OpenRawBeaconState, OpenRawBlock
and OpenRawExecutionPayloadEnvelope returning *api.RawResponse (body plus
the metadata needed to tell a complete transfer from a truncated one), a
dedicated per-node transport with connection and in-flight request caps,
typed HTTP status errors, and the raw response leak counter.

#81 was merged prematurely and reverted in 8d66ce6; this restores the
same tree as new commits so it can go through review properly.
