New MCP tool + --ssh-version CLI flag. Bypasses the CODESYS IDE entirely: SSH to a CODESYS Control Linux PLC, sudo strings the boot application binary, extract the X.Y.Z.W literal of _MCP_PROJECT_VERSION.sVersion. Filters out 3.5.x.y CODESYS runtime versions automatically. Solves the case where the .project file is locked by another CODESYS instance, or no CODESYS install is reachable, but the PLC is. Read- only on the PLC (just strings the boot binary). Requires SSH key auth + passwordless sudo for /usr/bin/strings on the PLC. Both error paths surface exact-instructions error messages (PowerShell key install command, sudoers line) instead of opaque failures. Smoke-tested against codesys-pi (RPi running CODESYS Control 3.5.22) with MCPTest2 v1.5.0.0 downloaded -- correctly extracts 1.5.0.0 and filters out the 3.5.22.0 runtime version literal.
