Open-slide adds SVG logo search

This is a small feature with outsized practical value: the difference between a deck that feels autogenerated and one that feels finished is often just getting the right logos in fast.

• –Integrated logo search removes a common friction point for AI-made slide decks, especially for product, competitor, and company overviews
• –Using SVGL gives the feature immediate breadth and better branding fidelity than ad hoc image generation
• –It strengthens open-slide’s pitch as an agent-native slide runtime, not just another presentation wrapper
• –The update is more workflow polish than platform reset, which makes it a clear product_update rather than a launch
