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, err := CdpConnect(9222)
+if err != nil {
+    log.Fatal(err)
+}
+defer CdpClose(conn, 0)
+```
+
+## Notas
+
+El WebSocket se implementa desde cero usando `net.Dial` + handshake HTTP Upgrade + framing RFC 6455. Esto evita dependencias externas. Solo soporta frames no fragmentados (suficiente para CDP que envia mensajes completos).
+
+El struct `CDPConn` y toda la infraestructura WebSocket/CDP se define en `cdp_conn.go` dentro del mismo paquete `infra`.
+
+La goroutine `readLoop` enruta respuestas a channels por ID de mensaje. Los eventos CDP sin ID son ignorados (las funciones que necesitan eventos usan polling).
