fix(landing): disable search during auto-typing animation

Bug: Clicking Search mid-animation searched partial text like 'authen'
Fix: Added autoTyping prop to HeroSearch, button disabled during animation

- User can only search after manually typing
- Pressing Enter during animation does nothing
- Once user interacts, isTyping=false and search works normally
