 * ESLint rule that enforces Optional usage patterns instead of nullable returns and direct nullable function calls.
 *
 * This rule:
 * - Disallows functions returning `T | null` or `T | undefined`
 * - Suggests using `optional.from_nullable()` for direct function calls that return nullable types
 * - Suggests using `optional.from()` for complex expressions that evaluate to nullable values
 * - Provides auto-fix suggestions where possible
