feat(tooltip): add collision-aware popover mode

[yshmarov]

Hey amigo! 👋

Summary

• add an opt-in Tooltip(:popover) mode that renders real tooltip content in the browser top layer
• open on hover or focus and keep the tooltip inside the visual viewport with flip-and-shift positioning
• render one borderless arrow that follows the trigger after collision adjustment
• preserve classic data-tip rendering and add ARIA wiring, rich content support, documentation, and browser coverage

Usage

Tooltip(:popover, tip: "Helpful details") do
  Button(:circle) { "?" }
end

Register the bundled controller with lazyLoadControllersFrom("daisy_ui/controllers", application).

Summary by cubic

Adds an opt-in Tooltip(:popover) mode that renders real tooltip content in the browser top layer, avoiding clipping ancestors, and flips/shifts it to stay inside the visual viewport. Classic data-tip rendering is unchanged.

• Opens on hover or focus, closes on leave, blur, or Escape.
• Uses role="tooltip" and wires aria-describedby to the first interactive trigger.
• Positions with one borderless arrow that follows the trigger after collision adjustment.
• Preserves caller-supplied Stimulus controllers; stimulus: overrides the controller identifier and popover_id: sets a stable id.
• Rich content renders via the content sub-component, falling back to the tip string.
• Bundled daisy-tooltip Stimulus controller is auto-pinned for importmap-rails apps.

Migration

• Bundler users must import daisy_tooltip_controller.js and register it as daisy-tooltip.
