Align algorithmic-art viewer actions with skill requirements

So the viewer template had only Reset in the Actions section, but the skill expects Regenerate, Reset, and Download PNG. I'm not allowed to raise a pr but I can place it here for anyone to fix that has the permission How to: skills/algorithmic-art/templates/**viewer.html** : LINE 423: ``` <!-- Actions Section (ALWAYS KEEP THIS) --> <div class="control-section"> <h3>Actions</h3> <div class="button-row"> <button class="button secondary" onclick="regenerateArtwork()">Regenerate</button> //added <button class="button" onclick="resetParameters()">Reset</button> </div> <button class="button tertiary" style="margin-top: 8px;" onclick="downloadPNG()">Download PNG</button> //added </div> </div> ```
