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

Ejemplo

conn, _ := CdpConnect(9222)
CdpNavigate(conn, "https://example.com")

// Esperar hasta 10 segundos a que aparezca el contenido
if err := CdpWaitElement(conn, ".main-content", 10*time.Second); err != nil {
    log.Fatal("Timeout esperando elemento:", err)
}

Notas

Usa document.querySelector(selector) !== null como condicion. Si timeout <= 0 usa 10s por defecto. Los errores de CdpEvaluate durante el polling (pagina cargando) se ignoran y se reintenta en el siguiente ciclo.
