feat: Wave 6 — focus mode, cooking timer, memory admin

Focus mode (`focus/`):
- focus.start ("режим фокуса" / "focus mode"): three side-effects in one
  voice trigger:
    1. switch profile to "work" (silences fun/banter)
    2. enable Windows Focus Assist via registry tweak (QuietHours key)
    3. schedule a stretch reminder in 50 minutes through the persistent
       scheduler — so it survives daemon restart
- focus.stop: undoes all three, including cancelling pending stretch
  reminders by matching their scheduler name. Best-effort: any one
  failing doesn't block the others.

Cooking timer (`cooking/`):
- Recognises 16+ dish names (чай, кофе, омлет, яйца, макароны, паста,
  рис, гречка, картошка, курица, пицца, etc.) and starts a preset-
  duration scheduler reminder ("Сэр, чай готов.").
- Single Lua script, table-driven — adding a recipe is one line.
- EN phrases for the same dishes ("boiling pasta", "frying eggs", ...).

Memory admin (`memory_admin/`):
- memory_admin.count → speak fact count with full RU pluralisation.
- memory_admin.list → speak 5 most-recent + toast the rest.
- memory_admin.wipe → ONLY fires on "точно забудь все" prefix (not bare
  "забудь все") so we can't disaster-wipe by accident.
- Adds `long_term_memory::clear_all() -> usize` returning removed count
  + Lua binding `jarvis.memory.clear_all()`.
- One extra unit test for `clear_all`.

Tests: 139 → 140 (+1). Pack count: 92 → 95.
