Simplify exit cleanup - one question, full cleanup

Changes:
- Single question on exit: 'Clean history and remove traces?'
- If yes: runs full trace eraser automatically
- Auto mode skips all prompts, removes everything
- TRACE_ERASER_AUTO=yes flag for non-interactive mode

User experience:
- Exit (0)
- One question
- If yes: everything cleaned and removed automatically
- No multiple prompts
