Bump op-node to v1.19.5 (PLAT-740)

[sameersubudhi]

Summary

Bumps client version:

• op-node: v1.19.4 → v1.19.5

Upstream marks it optional, recommended for sequencers — the headline change is sequencer block production (#22241, #22238) plus its same-release freeze fix (#22360), none of which the Lisk image reaches (verifier only, no --sequencer.enabled). op-reth stays at v2.4.2.

• Linear: PLAT-740

Changes

#	File	Change
1	reth/Dockerfile	VERSION=v1.19.4 → v1.19.5; COMMIT → 30f5d5836cab8ee44cf118d70831be6d0f0a9d9c
2	README.md	op-node client version + release link → v1.19.5

Checks

#	Check	Result
1	COMMIT pin	Matches the dereferenced annotated tag op-node/v1.19.5 (30f5d5836cab8ee44cf118d70831be6d0f0a9d9c)
2	op-node-lisk-sepolia.patch vs v1.19.5 op-node/rollup/derive/system_config.go	git apply --check clean (hunk offset +6) — no patch update needed
3	GOLANG_VERSION=1.26	Still aligned with op-node's go.mod (go 1.26.0, toolchain go1.26.5)
4	superchain-registry submodule pin (embedded superchain-configs.zip)	Advanced 3d97455 → 7715c7d; only removes sepolia-dev-0 devnet configs and registry docs/tooling — lisk and lisk-sepolia untouched
5	just build-superchain-go recipe at v1.19.5	Present
6	Other version references (docker-compose.yml, .env.*, entrypoints, workflows)	None
7	op-reth	Already at latest upstream (v2.4.2) — no bump

No entrypoint, flag, env or peer-config change; no data migration.

Release

Draft v0.4.27 is staged against main and covers this PR only — v0.4.26 is at main head, so there are no other unreleased changes. Publish after merge.

Poem

A rabbit checks the version line,
Then pins the node commit just right.
From four to five, the docs agree,
The Docker build hops happily.
