Bug Fixes & Stability Improvements

A round of fixes across the platform to keep things running smoothly:

• GEO 360 counts search indexers like OAI-SearchBot, Claude-SearchBot, and Meta-WebIndexer as AI crawls. Citation crawls are now only the bots that fetch a page while answering a user, like ChatGPT-User. Citation crawl totals drop by as much as AI crawl totals rise, and page categories can shift after each project's next daily update.
• Alexa runs that hit the provider's limit go out again as soon as there's room, instead of an hour later.
• Instagram captions that start with a blank line show their first line again.
