Small Fixes and Improvements

A few smaller changes that shipped this week:

• The Google Ads, Meta and LinkedIn agents can write and run code in a sandbox of their own. When a question needs a lot of API calls or real number crunching, the agent scripts it instead of working through it one call at a time. Your ad account credentials never enter the sandbox.
• The agent can search the web and read any page you point it at. Web search is listed under Integrations with your other data sources, so you can switch it off there.
• Every ad in the ad library has its own link. Open an ad, click Copy link, and whoever you send it to lands on that exact ad.
• Pending invitations can be cancelled, and you can change an invitation's access level before it's accepted without sending a new one.
• If you've been invited into more than one organization, the organization switcher lets you move between them.
• The skill and campaign menus you open with / and @ in chat stay on screen wherever your cursor is.
