fix hexai-tmux-edit agent detection, multi-line extraction, and clearing

- Reorder agents: cursor first to avoid false positive from "Claude 4.5
  Sonnet" model name appearing in cursor panes
- Change cursor detect pattern to box-drawing UI elements instead of
  name-based matching
- Change claude detect pattern to ❯ prompt instead of generic "claude"
- Support multi-line prompt extraction using last-contiguous-block
  algorithm to ignore command-review and dialog boxes
- Fix deduplicateText to always return full edited text (clear + resend)
  instead of stripping original prefix which caused double-removal
- Replace vim-style clear (Escape gg dG i) with universal End+BSpace*200
  since cursor's prompt is not actually vim
- Add Key*N repeat syntax in ClearKeys (parsed by parseKeyRepeat, sent
  via tmux send-keys -N)
- Add 300ms sleep after clear to let TUI drain queued backspaces before
  new text arrives
- Add debug logging to /tmp/hexai-tmux-edit.log
- Add strip pattern for "ctrl+c to stop" noise in cursor prompt
