Why HMS Dreadnought was not the point at Algeciras

How did the commissioning of HMS Dreadnought affect the Algeciras demonstration?

It was not the immediate point: the decisive influence came from the large, ready British fleet already assembled in front of the conference.

HMS Dreadnought's commissioning places the First Moroccan Crisis beside a major technical change. The immediate crisis, however, turned on the force visible under Beresford's command. Diplomats were responding to concentrated pre-dreadnought battleships already available for action, rather than the theoretical promise of one new ship. Deterrence depended on deployable force at a specific time and place.
