PR Summary

Medium Risk
Config loading is on the critical path for every node; native mode changes how secrets merge into nested JSON, though production paths still opt into explicit preset.

Overview
Introduces --config_format on the config CLI so --config_file can be interpreted in two ways. preset (default) keeps the existing flat dotted-key pipeline (layered files, pointers, env/CLI, #is_none). native loads a nested JSON base with serde, then merges flat dotted-key secret files into that tree before deserialization—skipping the preset pipeline.

Native loading requires exactly two config paths (base + secrets). set_nested_value applies secret keys at nested leaves, preserves siblings, can add missing leaves under existing parents, and ignores overrides whose path runs through null or missing intermediates (disabled optional components).

apollo_config gains ConfigFormat, clap derive, and NativeModeRequiresTwoConfigFiles, plus broad native-mode tests (deep secrets, optional None, single-file cases). Deployments and tests now pass --config_format preset explicitly (docker-compose sequencer nodes, K8s pod_builder, node_runner) so behavior stays on the legacy loader until native is adopted.

Native mode rejects one config file

High Severity

load_native accepts only exactly two --config_file paths via slice destructuring, yet ConfigFormat::Native, the CLI help, and test_native_config_single_file treat a lone base file as valid native loading without a secret file.
