Codesys-MCP-SP21-plus/tests/unit/script-manager.test.ts
Luke e374519fe1 Initial release: MCP server for CODESYS with persistent UI instance
v0.3.0 returning-watcher architecture — background thread polls for commands
and marshals execution onto the CODESYS UI thread, keeping the IDE fully
responsive between operations. File-based IPC with atomic writes, async mutex
command serialization, headless fallback, and 35 passing tests.
