egutierrez bf1efb2099 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

cdp_connect function go browser 1.0.0 impure func CdpConnect(port int) (*CDPConn, error) Se conecta al endpoint CDP en localhost:{port}. Obtiene el webSocketDebuggerUrl via HTTP /json/version, realiza el handshake WebSocket RFC 6455 sobre TCP puro (sin dependencias externas) y retorna una CDPConn lista para usar. Inicia goroutine de lectura de mensajes.

Ejemplo

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).
