* op-acceptance-tests: run acceptance tests in parallel

Add a native acceptance test runner that expands acceptance-tests.yaml gates
and schedules package-level go test runs concurrently, while preserving
the logs and junit artifacts expected by CI.

Remove shared-process-state blockers in acceptance tests and devstack
presets, convert the acceptance tree from SerialT to ParallelT, and
expand directory-only gate entries like interop/sync into concrete child
packages so the runner matches existing gate semantics.

ci: honor op-acceptance-tests no_output_timeout

ci: restore memory-all aggregator check

* op-devstack: add sysgo.SkipOnOpReth helper, skip two tests failing on op-reth

Skip TestSupernodeInteropInvalidMessageReplacement and
TestSupernodeSameTimestampInvalidTransitive when running with op-reth,
as they panic due to a safe head mismatch in EngineController
(ethereum-optimism#19411).

Introduces sysgo.SkipOnOpReth(t, reason) and the DevstackL2ELKindEnvVar
constant, replacing hardcoded env var strings in multichain_supernode_runtime.

* op-acceptance-tests: skip TestSupernodeSameTimestampCycle on op-reth

Same safe head mismatch panic as the other two supernode interop tests
(ethereum-optimism#19411).

* op-acceptance-tests: restore gate filtering for op-reth CI jobs

Add gate file system (op-acceptance-tests/gates/base.txt) to replace
the old acceptance-tests.yaml gate routing. The justfile reads package
lists from gate files and passes them to gotestsum.

- op-geth job runs all tests (no gate)
- op-reth jobs run only base gate packages
- Split per-test logs via split-test-logs.sh after test runs

* fix(ci): remove scheduled-docker-publish re-added during rebase

The rebase incorrectly re-introduced the scheduled-docker-publish
workflow and c-docker_publish_dispatch parameter that were removed
by ethereum-optimism#18821 and ethereum-optimism#19530 when docker builds migrated to GitHub Actions.
