feat: Wave 8 — bedtime/morning/coffee routine packs

routines/good_night:
- Switch profile to "sleep" (silences idle banter overnight).
- Cancel one-shot timers (Таймер:/Timer:/Кухня:/Cooking: name prefix)
  so a forgotten 6-hour reminder doesn't wake the user up.
- Speak a varied 5-line RU/EN good night with cancelled-count suffix.
- Deliberately does NOT lock PC / shut displays — too destructive
  without an explicit confirm step.

routines/good_morning:
- Switch profile back to "default".
- Report scheduled task count for the day.
- Speak a varied 5-line greeting with agenda preview.

routines/coffee_break:
- Pause idle banter so Jarvis isn't talking to an empty chair.
- Schedule a 5-minute check-in via the persistent scheduler.
- Speak a varied 3-line acknowledgement.

Pack count: 97 → 98 (one pack, three commands).
Tests: 140 still pass.
