Tether 2.1.0

Typed answers to Claude's questions now go through on multi-select questions, and later questions in a multi-question prompt are no longer skipped. The question panel shows send errors next to Submit, folds to one line from its header so you can read the chat, fits above the keyboard, and focuses the text box when you choose "Something else…". Permission prompts no longer show stray dashed lines in the dialog body.
