FitterWorker.stop() docstring describes removed thread-termination behavior

stop()'s docstring describes QThread.terminate() behaviour and refers to THREAD_TERMINATION_WARNING.md, but:

• the method only sets a flag (no termination), and
• that file does not exist in the repository.

The docstring documents code that was removed. Relatedly, analysis.py:448 still calls setTerminationEnabled(True) although nothing terminates.

Fix: Update the docstring to describe the flag-based stop; remove the stale setTerminationEnabled(True) call and the nonexistent-file reference.
