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)
+defer CdpClose(conn, 0)
+
+if err := CdpNavigate(conn, "https://example.com"); err != nil {
+    log.Fatal(err)
+}
+```
+
+## Notas
+
+Usa `Page.navigate` que es sincrono en la respuesta CDP pero la carga completa de la pagina puede tardar mas. Para esperar elementos especificos tras la navegacion, usar `CdpWaitElement`.
