Switch go-eth2-client to the ethpandaops fork and bump ethpandaops/beacon to its release/gloas branch so gloas SSE events, blocks and states are understood. Gloas (ePBS) blocks no longer embed the execution payload; they commit to it via a signed execution payload bid, which carries the payload's block hash but not its number. Teach the execution block trace path to fall back to the bid's block hash and resolve the block number from the execution node, retrying briefly to give the builder time to reveal the payload. Release plumbing, mirroring xatu: derive the goreleaser RELEASE_SUFFIX by anchoring on the semver core so multi-word suffixes like 'glamsterdam-devnet-7' survive intact, and tag suffixed images as ethpandaops/tracoor:<suffix> instead of <suffix>-latest.

Pin golangci-lint to v2.12.2 (matching xatu) instead of 'latest', read the Go version from go.mod, and exclude goconst for test files and the logging-vocabulary heavy agent/server/store packages. Bump the smoke-test Dockerfile builder to golang:1.26 to match the go.mod requirement. Claude-Session: https://claude.ai/code/session_012CnMNMdPisWGmvKhKzj1ii
Gloas (ePBS) blocks only commit to the execution payload; the payload contents ship separately as a SignedExecutionPayloadEnvelope, making the envelope effectively the other half of the block. Archive it as a new object type, cloned end-to-end from the beacon block flow: agent fetch on block events (gated on the gloas fork epoch, with a short retry while the builder reveals the payload; a never-revealed payload is skipped), gzip'd raw SSZ in the store, indexer table and gRPC/API surface, download route, retention, and a web UI listing. Envelope fetching rides on ethpandaops/beacon#80, which exposes GET /eth/v1/beacon/execution_payload_envelopes/{block_id}. Claude-Session: https://claude.ai/code/session_012CnMNMdPisWGmvKhKzj1ii

…retention (#565) Adds executionPayloadEnvelopes: 100h to the tracoor values template, matching the other object retentions. Tracoor archives signed execution payload envelopes on gloas networks (ethpandaops/tracoor#56); without this key the deployment falls back to the 30m default and purges them. https://claude.ai/code/session_012CnMNMdPisWGmvKhKzj1ii

Adds glamsterdam (gloas) support. Swaps go-eth2-client for the ethpandaops fork and bumps ethpandaops/beacon to its release/gloas branch. Gloas blocks commit to the execution payload via a bid instead of embedding it, so the execution block trace path now falls back to the bid's block hash and resolves the block number from the execution node, retrying briefly while the payload is revealed. Also reworks goreleaser suffix derivation so multi-word release branches like release/glamsterdam-devnet-7 produce ethpandaops/tracoor:glamsterdam-devnet-7 images, matching xatu.
Adds signed execution payload envelope archival as a new object type — in gloas the envelope carries the actual payload contents, so it is effectively the other half of the block. Cloned end-to-end from the beacon block flow: agent fetch on block events (gated on the gloas fork epoch, short retry while the builder reveals; never-revealed payloads are skipped), gzip'd raw SSZ storage, indexer table + API, download route, retention, and a web UI listing. Depends on ethpandaops/beacon#80 for the envelope endpoint.
Tested against glamsterdam-devnet-7 (lighthouse/geth): gloas beacon states, blocks, execution traces and payload envelopes are fetched, stored and indexed; stored envelope SSZ is byte-identical to the beacon node's response, and trace block hashes match the payload bids.
