Hermes Agent 4370ef4383 feat: landing page, link detail, 404 pages, auth redirect
- LandingHero: hero section with Heygo service intro + search input
- App.tsx: logged-in users auto-redirect to My Links
- LinkDetailPage: click-based stats/history toggle (hidden by default)
- 404 pages: styled with login prompt for private links
- Private redirect: pass alias to 404/login pages for redirect flow
- Mobile responsive: prevent text overflow on small screens
