Chunk Analyzer

- Added support for Minecraft 1.21.1+ – The plugin is fully compatible with server versions 1.21.1, 1.21.4, 1.21.11, and later (no code changes needed, as the API remains stable). - Fixed permission issue – The /ca menu command now requires the chunkanalyzer.use permission (granted to ops by default). Players without it will receive a dedicated no_permission message. - Added new localization strings – The config.yml now includes a no_permission entry for both English (en) and Russian (ru) language settings.
