Resolves:

• [App builder] Add disabled share button to app with tooltip “Save to share”
• [Sharing modal] Description content: “Anyone with this link can save or copy to edit this artifact” (removing the term “remix”)
• [Apps builder] Chat side - The input/prompt section cuts off the the helper text
• [Global Nav] Use selected style (cool-gray-10 background) for Tools and Knowledge items on the left bar nav.
• [Global Nav] On the left nav, can we use Cool gray 10 for the section separators
• [Global Nav] Some hovers are using gray 10 instead of cool gray 10. For example “Add new tool” button, the hamburger menu hover. Use cool gray always
• [Usage limit modal] For the “You’ve hit your usage limit” modal, we can just remove the CTA “Ok”.
• [Agent Builder] When I create a new agent from template and press save, a new agent from scratch is automatically loaded (the agent from template is also created as you can see it populate in the lefthand side mdenu).
• [App library - empty state] Replace static bee illustration with blinking/wings shaking bee. Animation file here. Figma prototype
• [Error page] We have a new illustration for “We couldn’t find the app you were looking for” here

Not an issue here, but it might be a good practice to memoize it, the object is recreated on each render.

Good point. I changed it.
