Gets the MA (main correct) solution from solutions array.
Array of solution configurations
The MA (main correct) solution
If no MA solution found (should never happen if ensureMainSolutionExists called first)
const mainSolution = getMainSolution(config.solutions);// Returns: { name: 'main', source: 'Solution.cpp', tag: 'MA' } Copy
const mainSolution = getMainSolution(config.solutions);// Returns: { name: 'main', source: 'Solution.cpp', tag: 'MA' }
