Supported parameter count

Stored supported parameters from the OpenRouter catalog. 460 of 463 models list at least one distinct parameter. 3 have no list and stay off the page. The highest count is 24, for TypeSafe: Jev Router and Pareto Code Router. The number is how many distinct parameters that model lists. A longer bar is more listed parameters. This count is separate from the model weight count and from how many models share one parameter name. A model with no stored parameter list stays off the page.
