feat: recover portfolio pages from scratch workspaces

- Add base layouts (BaseLayout, BlogLayout, ProjectLayout)
- Add UI components (Header, Footer, Navigation, Card, Tag)
- Add About page with personal story
- Add Projects pages (index, detail)
- Add homepage content
- Add SEO files (robots.txt, webmanifest)

Work was done by agents in isolated workspaces.
Consolidated into main repo for proper git tracking.

+          Después de años trabajando como desarrollador, decidí dar el salto al emprendimiento 
+          tecnológico. Vi una oportunidad en el mercado español: muchas soluciones B2B están 
+          dominadas por empresas extranjeras que no entienden las particularidades del mercado 
+          local, especialmente en temas de cumplimiento normativo.
+        </p>
+        <p class="text-text-secondary leading-relaxed mb-4">
+          Mi enfoque es construir en público, compartiendo tanto los éxitos como los fracasos. 
+          Creo en la transparencia y en la comunidad indie, y quiero contribuir al ecosistema 
+          de emprendedores españoles compartiendo mi viaje.
