Reor now has tabs and a new and improved design thanks to @milaiwi 🥳🥳🥳

• Patch fix on search

Reor now has a writing assistant feature! 🥳🥳🥳

• You can now use an LLM in-editor to help draft, summarise, rewrite or anything else right inside the editor!
• We think this is a killer feature that takes Reor to the next level. You can much more quickly organise and iterate on ideas as you're writing them.

Massive thanks to @weilirs for implementing this end to end!
