Minecraft2Shell 2.3.0 для Minecraft 26.1.2 (Fabric)

Replace hardcoded error strings in ShellCommand with localized messages via LanguageManager. getBetterErrorMessage was refactored to inspect a lower-cased message and return appropriate localized keys (including network/io/unknown cases) and some messages now append the original exception text. Also updated config import/export and file save error handling to use localized "error.invalid_path" and "error.file_cannot_save" messages. Added corresponding localization keys to en.json and tr.json for: error.cannot_run_program, error.access_denied, error.permission_denied, error.file_not_found, error.invalid_path, error.file_cannot_save, error.command_not_found, error.network_error, error.io_error, and error.unknown.
