feat(v0.5.0): history + streak + heatmap, quiet hours, partial reps, README

== История и стрики (#1) ==
- HistoryEntry { ts, exerciseId, action: done|skip|snooze, actualReps? }
  персистится в app-state.json, лимит 10k записей (~3 года), trim oldest 10%
- markDone/snooze/skip пишут в историю; markDone принимает optional actualReps
- IPC: getHistory(sinceMs?), clearHistory(beforeTs?) + preload bindings
- Renderer helpers (src/renderer/src/lib/history.ts):
  * dayKey(ts) — YYYY-MM-DD local
  * dailyReps(entries, exs, dayKey) — суммирует actualReps || planned
  * dailyRepsRange(entries, exs, days) — для heatmap, заполняет gaps нулями
  * currentStreak(entries) — consecutive days, today или yesterday (grace)
- Dashboard теперь 4 hero-карточки: Today (повторов за день) / Streak
  (дней подряд) / Next / Tracking
- Новый компонент HistoryHeatmap — GitHub-style 12-недельный календарь
  с 5 интенсивностями, локализованными подписями дней/месяцев

== Тихие часы (#2) ==
- shared/types.ts: QuietHours { enabled, from, to, days[] } + isQuietAt()
  helper с правильной обработкой wrap-around окон (22:00→08:00)
- DEFAULT_SETTINGS.quietHours = disabled, 22:00→08:00, все дни
- main/scheduler.ts: проверка isQuietAt перед fire; deferred fires
  поднимаются после окончания окна
- Settings UI: новая секция "Тихие часы" с toggle, time-pickers,
  day-of-week pills

== Сделал частично (#3) ==
- ReminderApp: stepper [−][число][+] вокруг счётчика повторов
- При adjusted (actualReps !== exercise.reps) число подсвечивается accent
  и появляется подпись "Засчитаем X из Y"
- markDone передаёт actualReps только если юзер реально изменил —
  иначе undefined чтобы история фиксировала планируемое значение чисто

== README.md (#4) ==
- Описание, фичи, скриншоты (TODO-плейсхолдер), установка, dev-команды,
  архитектура, тесты, stack, ссылка на RELEASING.md
- Бэйджи version / tests / platform

== i18n ==
- ~14 новых ключей × 2 языка: dashboard.stat.today_done, streak,
  settings.quiet.* (3 row'а), reminder.partial

== Тесты — 51 (было 33) ==
- shared/quiet-hours.test.ts (5): disabled, same-day, wrap-around,
  day filtering, zero-length
- renderer/lib/history.test.ts (13): dayKey, dailyReps (planned vs
  actual vs ignore non-done), currentStreak (empty, today gap,
  consecutive, yesterday grace, multi-entry same day), dailyRepsRange
