### check_visa

Check whether a visa is needed to enter the UK for a given nationality and travel purpose. Navigates the GOV.UK multi-step visa checker flow and returns the outcome including whether a visa is needed, the outcome title, and detailed guidance text. For multi-step flows with additional questions (e.g. work duration, family travel), the checker answers 'no' to yes/no questions and picks the first option for other choices to produce a general-case result.
