zNxPiglinRush

🔥 v2.0.0 — Architecture Overhaul

Complete rewrite of the plugin internals. Same behaviour on the surface, professional-grade code underneath. Drop-in update — just swap the jar and run /pr reload.

---

🏗️ Package Restructure

The entire codebase has been reorganised into a clean, domain-driven package layout under dev.znxki.zNxPiglinRush:

Old package	New package
config.engine	spawner.strategy
config.registry	spawner.registry
config.spawner	config (→ SpawnerDefinition)
events	listener
hook	integration
stats.repository	stats.storage

Main class renamed from ZNxPiglinRush → PiglinRushPlugin.

🧩 Interface-backed Architecture

Four new API interfaces introduced under dev.znxki.zNxPiglinRush.api:

• SchedulerService — abstracts Folia vs Spigot/Paper scheduling. Two implementations: FoliaSchedulerService and BukkitSchedulerService, selected at runtime via SchedulerServiceFactory
• SpawnStrategy — strategy pattern for spawn behaviour. Implementations: StandardSpawnStrategy and WaveSpawnStrategy. SpawnLocationResolver extracted as a shared utility
• StatsProvider — read-only interface over spawn statistics. SpawnTracker (ex SpawnStats) implements it
• StorageBackend — persistence abstraction. SqliteStorageBackend is the built-in implementation

---

⚙️ Config Updater

New ConfigUpdater automatically migrates old config files to the current schema without overwriting user values:

• Detects config version via config-version field (absent = legacy v1)
• v1 → v2: moves flat keys (spawn-count, spawn-cooldown, etc.) into spawners.magma_block.*, preserving all user-set values
• Creates a timestamped backup (config_backup_YYYYMMDD_HHmmss.yml) before any migration
• Fills missing keys from bundled defaults on every startup — future updates add new options automatically

🔧 Other Improvements

• ModrinthUpdateSource extracted from UpdateChecker — HTTP logic is now separate and swappable
• SpawnContext record introduced — passes spawn event data cleanly into strategy implementations
• Fixed update-checker permission check: was magmaspawner.admin, now correctly piglinrush.admin
• Fixed getMagmaConfig() leftover reference — now getPluginConfig()
• Renamed: HeatmapManager → HeatmapService, DiagnosticsMonitor → DiagnosticsService, BlockSpawnerConfig → SpawnerDefinition, PiglinRushConfig → PluginConfig
