PR Summary

Medium Risk
Touches production hybrid deployment merge paths; incorrect include resolution or drift from removed inline keys could change probes, env, ports, or sequencer settings at deploy time.

Overview
Hybrid sequencer overlays for mainnet, sepolia-alpha, and sepolia-integration now pull shared settings via include: from configs/overlays/hybrid/common/ instead of duplicating them in each environment.

Per-env YAML keeps only deltas (e.g. image tag, chain_id, feeder/recorder URLs, L1 contract addresses, batcher/consensus/state-sync overrides). Removed from env files: repeated image metadata, fee-token and versioned-constant keys, health probes, GCP monitoring, env (RUST_LOG, RUST_BACKTRACE, NO_COLOR), Kubernetes service ports, configList paths, inter-service components URLs/ports, and most shared sequencerConfig blocks—those live in the common layer. Gateway/mempool overlays can be include-only.

merger._load_common_yaml now loads common.yaml through DeploymentConfigLoader._load_one_file_with_includes (with config_base_dir) so overlay common files resolve include: the same way service configs already do.
