Fix ESLint import ordering and remove unused code

- Cleaned up CLI imports to match our ESLint ordering and dropped
  stray unused symbols (cli/src/chat.tsx:1, cli/src/utils/theme-
  system.ts:1, cli/src/hooks/use-system-theme-detector.ts:1).
- Removed unused locals from the chat message renderer and send-
  message flow so lint no longer complains about dead code (cli/
  src/components/message-block.tsx:181, cli/src/hooks/use-send-
  message.ts:58).
- Updated tooling imports at the bottom of chat.tsx so type-only
  dependencies sit in the dedicated group ESLint expects (cli/
  src/chat.tsx:31).
