Depends on alpha release of new SDK changes
dcode's system prompt appears as though it was intended to replace the base system prompt instead of augmenting it (some of the sections are almost identical).
#4437 introduced a mechanism to overwrite the base prompt. Here we apply it in dcode.
Review system prompt snapshot for effective changes.
