Plugin Manager

ummary: Release 1.2.0 adds full install/update management, a robust GUI, Modrinth compatibility improvements, and persistent tracking for managed plugins. Added Persistent managed-plugin registry: managed-plugins.yml (tracks project slug/ID for updates). Bulk update: /pmr update all stages updates and reports summary (updated / up-to-date / skipped / failed). Safe update staging: downloads updates into server update folder for restart-based replacement. Dynamic install attempt: plugin download + best-effort dynamic load after install. Paginated GUI with controls: previous/next/refresh/close, stable slot→plugin mapping. Expanded Modrinth search filters and loader support: includes paper, spigot, bukkit, purpur, folia. Game-version fallback: matches full and major.minor (e.g., 1.21.4 and 1.21). Changed Version bumped to 1.2.0 (pom.xml, plugin.yml, README, QUICKSTART). Improved install/update flows to track project slugs and avoid replacing wrong files. Replaced fragile GUI name-parsing with slot mapping and pagination. Shade packaging remains but documentations updated to new artifact name. Fixed / Improved Uninstall now attempts immediate file deletion and falls back to renaming (.disabled); removes entry from managed registry. More robust Modrinth API URL encoding and download target handling. Better asynchronous handling — network work off main thread and scheduler usage for UI messages.
