44d0e580f6* Pinned server-everything, fixed all tests to work with current pinned version, fixed problem with undetected failures (isError: true payloads). * First working vitest implementation * Refactoring some single-use configs fixtures and into the refeencing tests * No tests refere to server-everything (or any other server from a registry), all tests actually validate what they say they test. * Removed server-everything dep from CI, minor cleanup * Addressed Claude PR review comments: Added tsx dev dependency, beefed up process termination (possible leak on Windows), beefed up http server cleanup (close all connections), removed unused hasValidJsonOutput, reduced CLI timeout to give it breathing room with vitest timeout. * Made both stdio and http test servers fully composable, cleaned up types, terminology, and usage.
