### Added
- **WorldEdit / FAWE schematic support** — arenas can now be created from a `.schem` / `.schematic` file saved in the WorldEdit or FAWE schematics folder; use `/bw arena create <name> -sche <schematic>` (WorldEdit or FastAsyncWorldEdit soft dependency)
- **PlaceholderAPI support** — `NewBedwarsExpansion` registers 14 placeholders under `%newbedwars_*%`; PlaceholderAPI is a soft dependency so the plugin loads normally without it
- Per-player: `%newbedwars_arena%`, `%newbedwars_status%`, `%newbedwars_team%`, `%newbedwars_kills%`, `%newbedwars_final_kills%`, `%newbedwars_beds_broken%`, `%newbedwars_players%`, `%newbedwars_max_players%`, `%newbedwars_is_spectator%`, `%newbedwars_phase%`
- Per-arena: `%newbedwars_arena_<name>_status%`, `%newbedwars_arena_<name>_players%`, `%newbedwars_arena_<name>_max_players%`, `%newbedwars_arena_<name>_phase%`
- **Per-arena resource pack forcing** — `/bw setResourcePack <url|clear> [sha1hash]` sets a resource pack that is sent to every player who joins the arena; SHA-1 hash optional; use `clear` to remove
- **`/bw gamerule <name> <true|false>`** — set any per-arena gamerule from within setup mode without editing files; tab-completes both gamerule names and boolean values
- **More languages** — German (`de`), Spanish (`es`), French (`fr`), and Russian (`ru`) language files added; missing keys automatically fall back to English so partial translations still work fully

### Fixed
- **Sharpness not applied on sword purchase** — buying a sword from the shop now immediately applies the team's current Sharpness upgrade level; previously the enchant was only present after death/respawn
- **Potion effects broken on Paper 1.20.1** — right-clicking a custom potion now reliably applies the effect on all supported server versions; a two-layer approach (cancel in `PlayerInteractEvent` + fallback `PlayerItemConsumeEvent`) with next-tick scheduling ensures exactly one effect application regardless of how a specific Paper build handles the drinking animation
- **Blast-proof glass not protecting blocks below** — explosion handler now also removes from the explosion list any placed block that has blast-proof glass directly above it (one Y-level up)
- **Player can drop sword with Q key** — `PlayerDropItemEvent` now cancels sword drops during an active game while still allowing players to move items into chests
- **Schematic error shows literal `/name/`** — the `SchematicNotFound` message now substitutes the actual schematic name into the `/name/` placeholder before sending
- **`Objective.isRegistered()` compile error in `NScoreboard`** — `isRegistered()` does not exist in the Paper 1.17 API; replaced with plain `obj != null` checks
- **Arenas not cleaned up on server disable or reload** — `onDisable()` now calls `forceShutdown()` on every arena (cancels all tasks, teleports players to lobby, clears scoreboards and boss bars, removes ender dragons — skips world rollback which is unsafe during JVM shutdown); `reloadAll()` calls `stop()` (full rollback) on arenas with active players before clearing the arena maps, so worlds are cleanly reset and reloaded correctly
- **Schematic lookup only searched plugin folder** — schematic resolution now checks the WorldEdit / FAWE schematics directory as a fallback when the file is not found in the plugin's own folder
- **26.2 support**
