Summary: - Original command is in SSH_ORIGINAL_COMMAND, not normal argv. - Use PhutilShellLexer to parse it. - Fix a protocol encoding issue with ConduitSSHWorkflow. I think I'm going to make this protocol accept multiple commands anyway because SSH pipes are crazy expensive to build (even locally, they're ~300ms). Test Plan: With other changes, successfully executed "arc list --conduit-uri=ssh://localhost:2222".
