refactor(core): update all classes for new config system + add tab completion

BREAKING CHANGE: Core classes updated to use new section-based config

Updated classes:
- Mine.java - uses RegionConfig, BlockConfig, new FillMode
- Mines.java - uses new ConfigLoader.ConfigLoadException
- MineFileManager.java - creates configs with new system
- MineRepository.java - uses new ConfigLoader
- MaskScanService.java - uses BlockKey for markers
- BukkitBlockSetter.java - uses Map<BlockKey, Double>

Handlers updated:
- ActionBarHandler.java - uses UIConfig with MiniMessage
- MineBlockHandler.java - uses ResetConfig
- MineRewardHandler.java - uses RewardConfig
- MineResetHandler.java - uses new config sections

Commands updated:
- MaskCommands.java - updated exception handling

Added:
- LoMinesTabCompleter.java - Bukkit tab completion for all commands
- RegistrationManager.registerTabCompleter() - registers tab completer

Removed:
- Old ConfigLoaderTest.java (uses deprecated config system)

All classes now use:
- Type-safe BlockKey instead of String
- Section-based config (region, blocks, reset, rewards, ui, teleport)
- Duration-based intervals instead of ticks
- MiniMessage formatting for action bar

 # LoMines - TODO List (Обновлено: 2026-05-31)
 
-> **Статус проекта:** Рефакторинг завершен, пакеты изменены com.loki -> dev.loki  
+> **Статус проекта:** ✅ Система конфигурации полностью переписана  
 > **Базовая библиотека:** LoAPI (jar из `libs/lolib*.jar`, сейчас 3.0.0)  
 > **Версия Minecraft:** Paper 1.21.4  
 > **Java:** 21  
-> **Цель:** Привести код к стандартам качества + убрать зависимость от AXAPI
+> **Пакет:** dev.loki.lomines (изменен с com.loki)
 
 ---
 
-## 📋 Общий прогресс
+## ✅ Что сделано сегодня (2026-05-31)
 
-- [x] **Phase 1:** Структура проекта и конфигурация (5/5) ✅
+### 1. Рефакторинг пакетов ✅
-- [x] **Phase 2:** Core классы и handlers (тикер, reload) ✅
+- `com.loki` → `dev.loki`
+- Все Java файлы обновлены
+- `plugin.yml` обновлен
+- Исправлены импорты в тестах
+
+### 2. Полная перепись системы конфигурации ✅
+
+#### Новая архитектура (Section-based):
+```
+data/config/
+├── block/
+│   ├── BlockKey.java          # Sealed interface: Vanilla, Oraxen, ItemsAdder
+│   ├── BlockConfig.java       # Type-safe block weights
+│   └── FillMode.java          # CUBOID / MASK
+├── region/
+│   └── RegionConfig.java      # Cuboid regions
+├── reset/
+│   └── ResetConfig.java       # Duration, triggers, commands
+├── reward/

+├── teleport/
+│   └── TeleportConfig.java    # Teleport on reset
+├── ui/
+│   └── UIConfig.java          # Action bar, timer format
+├── MineConfig.java            # Composed record
+└── ConfigLoader.java          # Clean loader with YAML inheritance
+```
+
+#### Удалена старая система:
+- ❌ `ConfigParser.java` (464 строк)
+- ❌ `ConfigValidator.java` (валидация размазана)
+- ❌ `ConfigSerializer.java` (сериализация размазана)
+- ❌ `MineConfigBuilder.java` (builder внутри record)
+- ❌ `parser/ConfigParseException.java`
+- ❌ Старый `MineConfig.java` (17 полей)
+
+#### Новые возможности:
+- ✅ **Type-safe BlockKey** — sealed interface с Vanilla, Oraxen, ItemsAdder
+- ✅ **Human-readable durations** — "5m", "30s", "2h", "1d"
+- ✅ **YAML inheritance** — `defaults.yml` + перезапись в mine.yml
+- ✅ **MiniMessage** — форматирование action bar и предметов
+- ✅ **Immutable records** — все конфиги неизменяемы
+- ✅ **Валидация на уровне конструктора** — fail-fast
+

-## 🟡 НАРУШЕНИЯ ПРИНЦИПОВ (Приоритет 2) - ИСПРАВЛЕНО ✅
+## 📁 Структура проекта
 
-### KISS (Keep It Simple, Stupid) ✅
-- [x] Упростить `ConfigLoader` — разбито на Parser, Validator, Serializer ✅
-- [x] Упростить парсинг наград — используется RewardParser ✅
-- [x] Убрать сложную логику из команд — вынесено в сервисы ✅
-
-### DRY (Don't Repeat Yourself) ✅
-- [x] Создать `ValidationUtils` для повторяющейся валидации Material ✅
-- [x] Создать `ErrorHandler` для унифицированной обработки ошибок ✅
-- [x] Создать `MineRepository` для устранения дублирования ✅
-- [x] Унифицировать форматирование сообщений через MessageFormatter ✅
-
-### SOLID ✅
-- [x] **S**: ConfigLoader разделен на Parser, Validator, Serializer ✅
-- [x] **S**: MineCommands разделен на Admin, Player, Stats, Mask команды ✅
-- [x] **S**: Mines разделен на MineFileManager, MineRepository ✅
-- [x] **I**: MineConfig с Builder pattern ✅
-- [x] **D**: Repository pattern для доступа к данным ✅

+## 🐛 Технический долг
 
-### 🔴 Критический - РЕШЕНО ✅
+### 🔴 Критический (нужно сделать)
-- [x] `ConfigLoader` — разбито на 4 класса ✅
+- [ ] Обновить Mine.java для использования новой конфигурации
