fix: console output to stderr for clean --json output

- Change Console() to Console(stderr=True) so all status/progress
  messages go to stderr, keeping stdout pure JSON when --json is used
- Add missing exception handling in likes command for fetch_user
- Fix SKILL.md: favorite -> favorites (correct command name)
