fix: slash autocomplete only at input start + add bookmark commands

- Fix slash command autocomplete to only trigger when / is at the
  beginning of input text (position 1 in TipTap), not in the middle
  of messages
- Add /bookmark command to add NIP-29 group to user's kind 10009 list
- Add /unbookmark command to remove group from user's kind 10009 list
