fix: reset training session tracking, add error logging, fix list truncation

- Call `TrainingPrompt.resetSession()` at session start (step === 1)
  to prevent applied counters from growing unbounded across sessions
- Add structured error logging to all three training tools
- Add truncation indicator (`...`) when training list preview is cut off
