fix: Reduce component flashing on page load and scroll

- Remove mounted state checks that return null (Hero, About, Projects)
- Reduce animation delays and durations for faster initial render
- Change viewport margins from -100px to -50px for earlier trigger
- Reduce initial animation distances (y: 40 -> 20, y: 30 -> 20)
- Use requestAnimationFrame for Header mount to prevent flash
- Always render components instead of returning null to prevent layout shift
- Optimize Framer Motion transitions for smoother scrolling
