gloas: add builders registry + state fields

## Review after #16059 

**What type of PR is this?**
Feature

**What does this PR do?**
This PR introduces logrus writer hooks into the logging of prysm.
when log-format is text:
- set the default logrus output to be `io.Discard`
- create a writer hook for terminal, with formatting and coloring
enabled.
- create a separate writer hook for log-file (if enabled), without
coloring.

This immediately allows for having formatted/colored terminal logs,
while keeping the log-file clean.

+## [v7.1.0](https://github.com/prysmaticlabs/prysm/compare/v7.0.0...v7.1.0) - 2025-12-10
+
+This release includes several key features/fixes. If you are running v7.0.0 then you should update to v7.0.1 or later and remove the flag `--disable-last-epoch-targets`. 
+
+Release highlights:
+
+- Backfill is now supported in Fulu. Backfill from checkpoint sync now supports data columns. Run with `--enable-backfill` when using checkpoint sync.
+- A new node configuration to custody enough data columns to reconstruct blobs. Use flag `--semi-supernode` to custody at least 50% of the data columns.
+- Critical fixes in attestation processing.
+
+A post mortem doc with full details on the mainnet attestation processing issue from December 4th is expected in the coming days. 
+
+### Added
+
+- add fulu support to light client processing. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15995)
+- Record data column gossip KZG batch verification latency in both the pooled worker and fallback paths so the `beacon_kzg_verification_data_column_batch_milliseconds` histogram reflects gossip traffic, annotated with `path` labels to distinguish the sources. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16018)
+- Implement Gloas state. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15611)

+- Integrate state-diff into `State()`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16033)
+- Implement Gloas fork support in consensus-types/blocks with factory methods, getters, setters, and proto handling. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15618)
+- Integrate state-diff into `HasState()`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16045)
+- Added `--semi-supernode` flag to custody half of a super node's datacolumn requirements but allowing for reconstruction for blob retrieval. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16029)
+- Data column backfill. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15580)
+- Backfill metrics for columns: backfill_data_column_sidecar_downloaded, backfill_data_column_sidecar_downloaded_bytes, backfill_batch_columns_download_ms, backfill_batch_columns_verify_ms. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15580)
+- prometheus summary `gossip_data_column_sidecar_arrival_milliseconds` to track data column sidecar arrival latency since slot start. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16099)
+
+### Changed
+
+- Improve readability in slashing import and remove duplicated code. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15957)
+- Use dependent root instead of target when possible. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15996)

+- Use explicit slot component timing configs. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15999)
+- Downgraded log level from INFO to DEBUG on PrepareBeaconProposer updated fee recipients. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15998)
+- Change the logging behaviour of Updated fee recipients to only log count of validators at Debug level and all validator indices at Trace level. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15998)
+- Stop emitting payload attribute events during late block handling when we are not proposing the next slot. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16026)

+- Move `Origin checkpoint found in db` from WARN to INFO, since it is the expected behaviour. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16075)
+- backfill metrics that changed name and/or histogram buckets: backfill_batch_time_verify -> backfill_batch_verify_ms, backfill_batch_time_waiting -> backfill_batch_waiting_ms, backfill_batch_time_roundtrip -> backfill_batch_roundtrip_ms, backfill_blocks_bytes_downloaded -> backfill_blocks_downloaded_bytes, backfill_batch_time_verify -> backfill_batch_verify_ms, backfill_batch_blocks_time_download -> backfill_batch_blocks_download_ms, backfill_batch_blobs_time_download -> backfill_batch_blobs_download_ms, backfill_blobs_bytes_downloaded -> backfill_blocks_downloaded_bytes.

+# Graffiti Version Info Implementation
+
+## Summary
+Add automatic EL+CL version info to block graffiti following [ethereum/execution-apis#517](https://github.com/ethereum/execution-apis/pull/517). Uses the [flexible standard](https://hackmd.io/@wmoBhF17RAOH2NZ5bNXJVg/BJX2c9gja) to pack client info into leftover space after user graffiti.
+
+More details: https://github.com/ethereum/execution-apis/blob/main/src/engine/identification.md 
+
+## Implementation
+
+### Core Component: GraffitiInfo Struct
+Thread-safe struct holding version information:
+```go
+const clCode = "PR"
+
+type GraffitiInfo struct {
+    mu           sync.RWMutex
+    userGraffiti string  // From --graffiti flag (set once at startup)
+    clCommit     string  // From version.GetCommitPrefix() helper function
+    elCode       string  // From engine_getClientVersionV1
+    elCommit     string  // From engine_getClientVersionV1
+}
+```
+
+### Flow
+1. **Startup**: Parse flags, create GraffitiInfo with user graffiti and CL info.
+2. **Wiring**: Pass struct to both execution service and RPC validator server
+3. **Runtime**: Execution service goroutine periodically calls `engine_getClientVersionV1` and updates EL fields
+4. **Block Proposal**: RPC validator server calls `GenerateGraffiti()` to get formatted graffiti
+
+### Flexible Graffiti Format
+Packs as much client info as space allows (after user graffiti):
+
+| Available Space | Format | Example |
+|----------------|--------|---------|
+| ≥12 bytes | `EL(2)+commit(4)+CL(2)+commit(4)+user` | `GE168dPR63afBob` |
+| 8-11 bytes | `EL(2)+commit(2)+CL(2)+commit(2)+user` | `GE16PR63my node here` |
+| 4-7 bytes | `EL(2)+CL(2)+user` | `GEPRthis is my graffiti msg` |
+| 2-3 bytes | `EL(2)+user` | `GEalmost full graffiti message` |
+| <2 bytes | user only | `full 32 byte user graffiti here` |
+
+```go
+func (g *GraffitiInfo) GenerateGraffiti() [32]byte {
+    available := 32 - len(userGraffiti)
+
+    if elCode == "" {
+        elCommit2 = elCommit4 = ""
+    }
+
+    switch {
+    case available >= 12:
+        return elCode + elCommit4 + clCode + clCommit4 + userGraffiti
+    case available >= 8:
+        return elCode + elCommit2 + clCode + clCommit2 + userGraffiti
+    case available >= 4:
+        return elCode + clCode + userGraffiti
+    case available >= 2:
+        return elCode + userGraffiti
+    default:
+        return userGraffiti
+    }
+}
+```
+
+### Update Logic
+Single testable function in execution service:
+```go
+func (s *Service) updateGraffitiInfo() {
+    versions, err := s.GetClientVersion(ctx)
+    if err != nil {
+        return  // Keep last good value
+    }
+    if len(versions) == 1 {
+        s.graffitiInfo.UpdateFromEngine(versions[0].Code, versions[0].Commit)
+    }
+}
+```
+
+Goroutine calls this on `slot % 8 == 4` timing (4 times per epoch, avoids slot boundaries).
+
+### Files Changes Required
+
+**New:**
+- `beacon-chain/execution/graffiti_info.go` - The struct and methods
+- `beacon-chain/execution/graffiti_info_test.go` - Unit tests
+- `runtime/version/version.go` - Add `GetCommitPrefix()` helper that extracts first 4 hex chars from the git commit injected via Bazel ldflags at build time
+
+**Modified:**
+- `beacon-chain/execution/service.go` - Add goroutine + updateGraffitiInfo()
+- `beacon-chain/execution/engine_client.go` - Add GetClientVersion() method that does engine call
+- `beacon-chain/rpc/.../validator/proposer.go` - Call GenerateGraffiti()
+- `beacon-chain/node/node.go` - Wire GraffitiInfo to services
+
+### Testing Strategy
+- Unit test GraffitiInfo methods (priority logic, thread safety)
+- Unit test updateGraffitiInfo() with mocked engine client
