solid-js is being bundled twice in production and not in dev

In dev mode solid-js module is being dedup to ensure its only being bundled once. But when you build for production its not and thus solid-js can be bundled twice leading to side effects like createEffect not having a root because there are two solids running.

I think the solution is to always set dedup and optimizeDeps to the libraries you have listed to prevent them from being bundled twice or be able to pass in dedupe: [...nestedDeps, ...solidPkgsConfig.nestedDeps]

This is related to: https://github.com/solidjs/solid/issues/1843 and is the root cause of that issue.

Inizia esaminando la configurazione di sviluppo e produzione del plugin relativa a dedup e optimizeDeps; l'issue non indica alcun file o test. Confronta il modo in cui solid-js viene incluso nel bundle in entrambe le modalità e considera la issue correlata di Solid come contesto. Il lavoro è completato quando le build di produzione evitano di includere solid-js due volte nel bundle, preservando al contempo il comportamento esistente in sviluppo.
