Detailed Description

Sink for solver progress/diagnostics (Dependency Inversion / SRP).

GaussSeidel and NewtonRaphson must only solve; reporting iteration progress and logging is a separate responsibility. Instead of calling LOG_* macros and printIterationProgress()/printConvergenceStatus() directly, the solvers report through this abstraction. A null observer pointer means "no reporting" – the solver remains pure numerically. Concrete observers (e.g. one that writes to the Logger singleton and the terminal progress bar) are injected by the caller, not hardcoded inside the solver.
