Class ParameterBuilder

Builds an inline object parameter with JSDoc comments for each property. Handles properties with special characters (like HTTP headers) using string literals.

Builds a standard method parameter.

Builds a params?: { query?: {...}; headers?: {...} } parameter, omitting the query or headers branches when their property list is empty. Returns null when both branches are empty.

Keeping query and headers in separate sub-objects (rather than one flat record) lets the runtime RequestBuilder apply each set under its own OpenAPI rules without having to disambiguate by name.
