None.

What does this implement/fix? Explain your changes.

This PR replaces two placeholder TODOs in the SVM user guide with a short explanation of the tol and max_iter parameters.

The added text explains that:

• tol controls the stopping criterion of the optimization
• smaller tol values can improve convergence accuracy at the cost of longer fit times
• max_iter limits how long the solver is allowed to run
• scaling the data and adjusting tol or max_iter can help when the solver struggles to converge

This is a documentation-only change and does not modify any API behavior.
