### NEW FEATURES
[1] Smooth teleport transition: pre-loads destination chunks plus short blindness/slow-falling/resistance so players don't see void. Configurable via `smooth_transition` block

### CRITICAL FIXES
[2] Nether RTP failing with `UNKNOWN: 50` — air check now uses `Material.isAir()` so CAVE_AIR and VOID_AIR match
[3] Shutdown crash `IllegalPluginAccessException` — FoliaScheduler runs one-shots inline when the plugin is disabled
[4] End RTP failing on unexplored chunks — `world_the_end` added to default location_cache, and `shouldGenerateChunks` default flipped to `true`
[5] `/rtp world` getting stuck on the cross-server queue when a server alias matched a local world name — parser now checks worlds first
[6] Action bar showed `1m 22ss` — removed trailing `s`, formatDuration already includes the unit
[7] Empty `""` lines in `chat_message` are no longer skipped
[8] `<x>` `<y>` `<z>` `<world>` `<player>` placeholders work in `effects.title`, `effects.action_bar`, `effects.chat_message`
[9] PlaceholderAPI placeholders (e.g. `%rp_left_click%`) now expand in RTP GUI items
[10] RTP GUI close button can be removed cleanly (`enabled: false`, missing slot, or empty section)
[11] RTP GUI decoration items honor `enchanted: true`
[12] `smooth_transition` and `zone_title` auto-apply to existing installs — config-version bumped to 33
[13] `zone_particles.yml` is now registered with ConfigUpdater so future fields migrate automatically

### IMPROVEMENTS
[14] `effects.teleport_delay_bar.text` from config.yml now beats `teleport.delay_actionbar` from messages.yml
[15] Title and action bar effects no longer return early on whitespace-only text
[16] zone_particles.yml updated

### FROM PULL REQUEST #10
[17] Folia chunk-ticket and `chunk.getEntities()` calls in PlayerListener now wrapped in `runAtChunk`
[18] `DatabaseManager.isConnected()` is non-blocking — volatile flag, async 30s validator, reconnect-storm guard
[19] `JustRTP.onDisable` null-safe when `rtpLogger` failed to init
[20] AnimationManager double-recreation removed from `reload` — active animations preserved
[21] `RTPMatchmakingManager.restart()` called from reload, plus `Math.max(1, tick_interval)` clamp
[22] `processMatch` fallback uses the verified-safe central location instead of the unverified offset point
[23] Rich `/rtp queue status` — position, waited time, ready indicator, other-world queues
[24] Global `zone_title` config block — default countdown title for all zones
[25] `<time>` placeholder works in zone `main_title` too
[26] `DataManager` lazy init rewritten with volatile + DCL

### CONFIGURATION
