Add ronin-mainnet and ronin-saigon op-reth (OP-stack migration, May 12 2026)

Ronin migrated from standalone sidechain to OP-stack L2 operated by
Conduit, with EigenDA V2 for data availability. New composes follow
conduitxyz/ronin-migration-reth-docker: conduit-op-reth fork +
op-node v1.16.5 + eigenda-proxy 2.7.0 relay.

- op/ronin/{mainnet,saigon}: Conduit genesis (bedrockBlock patched to
  55577500 / 45528550) and rollup.json (alt_da GenericCommitment injected)
- saigon is a NEW chain post-migration: chainid 202601, L1 sepolia
- also regenerated: xlayer-testnet composes (dshackle chain label was
  corrupted to 'ronin' by an override typo), native ronin/ronin composes
  (upstream labels follow new chain ids), reference-rpc-endpoint.json
