Custom vocabulary & tone, per note

## Background: If you use Cleft for both personal and professional notes, it can be weird to mix tones. For example, say I want the minutes of a meeting, then I'd like a formal tone. However, if I'm sending a note to a friend with a recommendation about what mirrorless camera to buy, I'd like it to have a more informal tone. ## Feature Description: A way to add custom vocabulary and tone for each individual note. ## Potential Implementation: It could be done either before you start recording (maybe select a couple of tags such as "output in Spanish", "formal", "informal", "shopping list"...). This would be the way to reduce your LLM processing, but it might break the UX. It could be done afterwards, with a text box similar to the one in AI preferences. That will allow you to re-process your note with a new tone.
