fix: complete React wrapper and fix docs API references

[Copilot]

Summary

Completes the React wrapper (react-monkeyjs) and fixes incorrect API references throughout the documentation.

---

React Wrapper (packages/react-monkeyjs/lib/context/TourProvider.tsx)

Problems fixed

Problem	Fix
Auto-started the tour with setTimeout(..., 1000) in useEffect	Removed — consumers call useTourContext().start() when ready
tour.start / tour.distroy passed directly to context, losing this binding	Wrapped in useCallback so binding is preserved
isTourActive was a static snapshot that never updated	Replaced with useState + window.addEventListener('onStart'/'onEnd') for reactive updates
Unused TourController import in type positions	Removed; used plain function types instead

---

Documentation Fixes

Every example in the docs used a non-existent API shape. The actual stepComponent type is:

{
  element: string;          // element ID — no '#' prefix
  title: string;
  description: string;      // not 'content'
  action?: () => Promise<unknown>;   // not onNext/onPrevious/onComplete
  condition?: () => boolean;         // not placement/showArrow
}

Files updated

File	What was wrong
StepComponentTable.astro	Table rows showed target, content, placement, showArrow, etc.
types.astro	StepComponent type had wrong field names
api.astro	Listed destroy() — actual method is distroy()
setup.astro	Step fields and placeholder tourConfig replaced with real config
configuration.astro	stepComponent type and full example used non-existent options
examples.astro	All 4 examples (basic, custom theme, React integration, event handling) used wrong fields and non-existent config keys (showOverlay, overlayOpacity, closeOnOutsideClick, etc.)
