/// Tooltip component with proper accessibility and positioning
///
/// The Tooltip component provides accessible tooltip functionality with
/// proper ARIA attributes, keyboard navigation, focus management, and flexible positioning.
///
/// # Features
/// - Proper tooltip semantics and accessibility
/// - Keyboard navigation (Enter, Space, Escape)
/// - Focus management and tab navigation
/// - Multiple variants and sizes
/// - State management (open/closed, hover/focus)
/// - Event handling (show, hide, toggle)
/// - Positioning options (top, bottom, left, right)
/// - Delay and duration controls
/// - Integration with form controls
///
/// # Example
///
/// ```rust
/// use radix_leptos_primitives::*;
///
/// #[component]
/// fn MyTooltip() -> impl IntoView {
///     let (isopen, set_isopen) = create_signal(false);
///     let (delay, set_delay) = create_signal(500);
///     let (duration, set_duration) = create_signal(300);
