Introduces a feature to announce bans of 30 minutes or longer to all players, configurable via the new 'announce_bans' option in config.toml. Updates documentation and example config, enhances DatabaseBanCommand to broadcast ban messages, and adds supporting methods in ProxyConfig. Also updates the build system for dynamic versioning, plugin metadata generation, and switches to the Shadow plugin for fat JAR creation. Project version is incremented to 1.2 across documentation.
