base-reth-node
- Upgrades Reth to v2.5.1with the release-line history-shard read and Engine API pending-handoff backports.

- Operational improvements: Publishesghcr.io/base/node, adds Mainnet and Sepolia node environment templates, groups Reth snapshot commands, adds EL peer ban/unban and reachability checks inbasectl, and keeps one month of history in the full preset.
- Bug fixes and stability improvements.

base-consensus
- L1 origin and derivation stability: Adds separate L1 RPC timeouts, L1 origin RPC metrics, prefetched L1 origin reuse, startup RPC retries, finality preservation across derivation resets, outage reorg coverage, and safer orphan detection.
- P2P and observability: Adds consensus-layer P2P reachability checks, EL sync probes, validator-only DA batcher sender overrides, and shadow candidate block metrics.
