cmake-server: Change message wrapper to avoid ambiguity with content

Change our message wrapper from

    [== CMake Server ==[ ... ]== CMake Server ==]

to

    [== "CMake Server" ==[ ... ]== "CMake Server" ==]

to guarantee that no JSON content can ever contain the ending string
(because it would be encoded as `]== \"CMake Server\" ==]`).
