herdr web ui v0.3.6

Added

• gjc and omo have their own marks in the sidebar and the chat. An omo pane is named omo even
  though herdr labels it pi or claude as omo works, so its mark no longer changes under you.
• gjc panes open in the chat view with their conversation, model and effort, like omp and omo.
  The chat follows the session the pane's gjc has open.

Fixed

• A request that failed (an authentication error, an overloaded provider) shows its error in the
  chat of an omp, omo or gjc pane. The prompt used to stand there with no answer at all.
