…on less than reported in the prepare header. Fixes #2052 * chore: route synchronous exceptions from packet deserialisation as a fatal connection error * chore: initial steps in migration to builtin node test runner * chore: add test:builtin-node-runner npm script * add a test case reproducing #2052 issue * add mysql:8.0.33 to linux matrix * debug test execution * cleanup debug log * simple connection test * simple connection test * end connection in the test * add timeout * fix: handle prepare response with actual number of parameter definition less than reported in the prepare header. Fixes #2052 * test commit * lint
