feat: duels player colors + elytra sub-modes (M-level)

- Add ParkourGenerator.selectBlockData() hook (forced course material);
  BlockSelector checks it first; SingleDuelsGenerator overrides to use the
  player's color (16 concrete colors) and forces only DEFAULT block type
- Elytra sub-modes: SpeedDemonGenerator (max-speed score), MinSpeedGenerator
  (min-speed check, reset on 6 slow ticks), TimeTrialGenerator (score cap),
  CloseGenerator (FLAT rings); + SpeedDemon/MinSpeed/TimeTrial/Close modes,
  registration, locales play.elytra.*, config mode-settings.*
- Config.getDouble(path, default) + ConfigAccessor overload
- checkstyle 0/0, PMD 0, build green

 ### Duels (перенос из `dev.efnilite.ipp`)
 
 - **122. Duels — модель «генератор на игрока».** ✅ **СДЕЛАНО**: `duels/` — `DuelsMode implements MultiMode`, `DuelsGenerator extends ParkourGenerator` (владелец: `Map<ParkourPlayer, SingleDuelsGenerator>`, allowJoining, goal, countdown), `SingleDuelsGenerator extends ParkourGenerator` (`getPlayers()=List.of(свой игрок)` → независимый state/history/score; при `state.score >= goal` → `owningGenerator.win`), `DuelsCountdown` (10с отсчёт + старт трасс). Результаты НЕ пишутся в лидерборд (`getLeaderboard()=null`). Тик через владельца (`tick()` тикает каждый single). Зарегистрирован (Modes.DUELS, PluginBootstrap, config.yml `modes.duels.{enabled,max-players,goal,island-distance}`, локали `play.multi.duels.*`).
-- **123. Duels — изменения ядра.** Частично: арены строятся вручную (плоские stone-платформы на сдвинутом Z), хук `selectBlockData()` в нашем коде отсутствует — цвет игрока реализован упрощённо (дефолтный материал; `setPlayerIndex`/`blockData` сохранены для будущего). `final Island` не трогали.
+- **123. Duels — изменения ядра.** ✅ **Добор**: добавлен хук `ParkourGenerator.selectBlockData()` (public, возвращает null по умолчанию) → `BlockSelector.selectBlockData()` первым делом проверяет его; `SingleDuelsGenerator` переопределяет → возвращает цвет игрока (16 concrete-цветов, `setPlayerIndex`) и форсит `defaultChances={DEFAULT:1.0}` + пустые specialChances (курс одноцветный, без спец/схем). Арены — плоские stone-платформы на сдвинутом Z (Island не трогали).
 - **124. Duels — классы:** `DuelsMode implements MultiMode` (create() реально создаёт сессию, join() через `isAcceptingPlayers`, **leave() только `removePlayer` без `ParkourUser.leave`** — фикс рекурсии Coop), `DuelsGenerator` (owner/allowJoining/playerGenerators/spawnData/goal; `initCountdown()` по клику LIME_BANNER 10с; `win()` с guard `stopped`; `reset(false)` синхронно и идемпотентно, НЕ `runLater`), `SingleDuelsGenerator` (`getPlayers()=List.of(player)`, `setPlayerIndex`→цвет, `score()`→`win` при goal).
 - **125. Duels — интеграция:** `modes.duels{enabled,max:2,target-score,island-distance}` в config.yml, локали `modes.duels.*`/`play.multi.*`, `MultiplayerMenu` (фильтр `instanceof MultiMode`) + кнопка в PlayMenu, баннер-старт в hotbar, `/lp create|join <player>|invite`. Сложность: **L**.
 - **126. Duels — не повторить баги:** Race (TIME-лидерборд, ресет в воздухе через `runLater`) — у Duels лидерборда нет, время брать из `state.start` своим форматтером, ресет только синхронно с null-guard; Coop (рекурсия, невозможность создать) — не вызывать `ParkourUser.leave` поверх unregister, сессию создавать в `create()`.

 - **127. Elytra — модель.** ~~...~~ ✅ **БАЗОВОЕ СДЕЛАНО**: `elytra/section/` (ElytraSection+KnotDirector+PointType+ClientBlockChanger, сплайн через commons-math3), `elytra/generator/ElytraGenerator extends ParkourGenerator` (свой tick/score/фолл/reset, sustained-буст +0.08 в ascending), `elytra/mode/ElytraMode`. Зарегистрирован (Modes.ELYTRA, PluginBootstrap, локали play.elytra.elytra). Команда commons-math3: `org.apache.commons:commons-math3:3.6.1` + relocate. Осталось по п.127: фейерверк-буст (`v*0.7+dir*0.6`) — сделано упрощённо (только sustained); CloseMode (FLAT-кольца).
 - **128. Elytra — клиент-сайд рендер.** ✅ `ClientBlockChanger`: очередь `Map<chunkX, Set<Vector>>`, `player.sendBlockChanges(states)` по чанкам, forward limit min(vd,8), flush/clear. Секции хранят Vector (без пиннинга чанков).
-- **129. Elytra — классы.** ✅ Базовый: ElytraSection/KnotDirector/PointType/ClientBlockChanger + ElytraGenerator + ElytraMode. Осталось (M): подклассы-режимы SpeedDemon/MinSpeed/TimeTrial/Close/Obstacle, фейерверк-буст, раздача элитр через PreviousData (сейчас элитры выдаются в слот нагрудника при generateFirst, глiding=true).
+- **129. Elytra — классы.** ✅ Базовый: ElytraSection/KnotDirector/PointType/ClientBlockChanger + ElytraGenerator + ElytraMode. ✅ **M-добор**: подклассы-режимы SpeedDemonGenerator (скор = макс. скорость), MinSpeedGenerator (поддержание мин. скорости, ресет при 6 тиках медленнее), TimeTrialGenerator (скор ограничен SCORE из конфига), CloseGenerator (FLAT-кольца); режимы SpeedDemonMode/MinSpeedMode/TimeTrialMode/CloseMode + регистрация + локали `play.elytra.{speeddemon,minspeed,timetrial,close}` + config `mode-settings.{min-speed,time-trial}`. Добавлен `Config.getDouble(path, default)`. Осталось: фейерверк-буст, раздача элитр через PreviousData, Obstacle-режим.
 - **130. Elytra — зависимости/мир.** ✅ commons-math3 подключён+relocated; отдельный мир не нужен (клиент-сайд); ASCEND_THRESHOLD_Y=50; скор в double (movementScore), в лидерборд пока не пишется (TODO: int-масштаб). Сложность: **S ✅**, M (режимы+бусты) и L (Obstacle+настройки+стили+награды) — далее.
 
 - **131. Тесты под новые режимы:** сплайн/секции (изоляция, Y/Z интерполяция), `ElytraGenerator.tick` (score по velocity.x, shouldReset-причины), `DuelsGenerator.win` (guard `stopped`, идемпотентность `reset(false)`), `SingleDuelsGenerator.score`→win при goal, рекурсия unregister (регрессия Coop).
