feat: externalize apps/analysis to Gitea repos, add analysis table

- Migration 007: repo_url on apps table + analysis table with FTS5
- Analysis struct, parser, CRUD, validation, hash computation
- Selective purge: remote-only apps/analysis preserved across fn index
- CLI: fn app list/clone/pull, fn analysis list/clone/pull
- search/show/list now include analysis results
- Apps removed from git tracking (content lives in Gitea repos)
- .gitkeep for apps/ and analysis/ dirs
- Bash functions: jupyter analysis pipeline, shell utilities
- Browser domain: CDP functions moved from infra to browser

+## Ejemplo
+
+```go
+conn, _ := CdpConnect(9222)
+CdpNavigate(conn, "https://example.com")
+
+// Esperar hasta 30 segundos a que la pagina cargue por completo
+if err := CdpWaitLoad(conn, 30*time.Second); err != nil {
+    log.Fatal("Timeout esperando carga:", err)
+}
+
+html, _ := CdpGetHTML(conn)
+```
+
+## Notas
+
+A diferencia de `CdpWaitElement`, que ignora errores de `CdpEvaluate` durante el polling (la pagina puede aun no estar lista), `CdpWaitLoad` retorna el error inmediatamente porque un fallo en `document.readyState` indica una conexion rota, no una condicion transitoria.
+
+Si `timeout <= 0` usa 30s por defecto (mas largo que `CdpWaitElement` porque la carga completa de red puede tardar mas que la aparicion de un elemento DOM).
