fix: isolate Alpine Node runtime and bound URL probes (#3104)

Pin Alpine amd64 to the verified upstream Node runtime without retaining temporary binaries in image layers. Bound fresh-process URL probes and verify serialized amd64/ARMv6 layers in CI. Keep existing Sequelize, SQLite and Debian runtime behavior unchanged.
