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)
+result, err := CdpEvaluate(conn, "document.title")
+// result = "My Page Title"
+
+sum, err := CdpEvaluate(conn, "1 + 2")
+// sum = "3"
+```
+
+## Notas
+
+Los valores no-string se convierten con `fmt.Sprintf("%v", value)`. Numeros aparecen sin decimales si son enteros (ej: `"3"` no `"3.0"`). Para tipos complejos (objetos, arrays), el resultado es la representacion Go de la interfaz, no JSON — usar `JSON.stringify(...)` en la expresion JS para obtener JSON limpio.
