Sync improvements + Auth sync with feedback board

Quality of life improvements

• Your Memex auth state is now synced with the feature/changelog/roadmap board, making it unnecessary to sign up on a separate platform to give feedback or engage in conversations.

• PDFs are now directly openable via the Google-Search results

  

• Big performance improvements for the lists sidebar drag & drop

Bug fixes

• 2 massive mystery sync bugs that we could finally figure out whats happening and fix

  • Page updates (like changing title) would overwrite the full text field. The same mechanism would make only Tweet title searchable as mentioned here @Full-text index Twitter threads/replies

  • Because of an untested URL normalisation dependency on React Native, in some cases annotations would not be associated with the right page, and thus seem "lost"

• Fix regression with AI queries not working on Dashboard
