Corporate email permutator (ranked) API

Classic OSINT primitive: given a first name, last name and corporate domain, generates the ranked, de-duplicated list of likely email formats (first.last@, flast@, first@, f.last@, last.first@, …) each with a confidence score derived from real-world pattern prevalence, after sanitizing diacritics and stripping protocol/www from the domain. The value-add: the exhaustive permutation set plus the ranking heuristic, deterministic where an LLM is vague. Answers 'likely email for this person', 'guess corporate email format', 'email permutations for first last at domain', 'most probable work email'.
