Module requests 

One struct per captcha type. Every struct implements CaptchaRequest.

Conventions used by all request types (keep them when adding a new one):

• Type::new(<required fields>) builds a request; optional fields are Option<_> public fields with chainable with_<field>(value) setters.
• Field names are snake_case; #[serde(rename = "...")] maps them to the exact API names (note websiteURL, not websiteUrl). None fields are not sent.
• "type" (and "class" for CustomTask) come from TASK_TYPE / CLASS, never from a field.
• Local checks that the API would reject anyway live in validate().
