ChallengeUtil

Introduce Connunity Hunt mode and related UI/logic, plus robustness improvements to full world reset.

• Add ConnunityHuntManager: automatic team assignment (Streamer vs Viewer), 2-minute viewer headstart (blindness/invulnerability), compass charging/usage, compass tracking with fallback portal search, glowing effects and visual particle feedback. Includes utility methods to manage teams and compass cooldowns.
• Add SpectatorCommand to allow hosts to become spectators in Connunity Hunt mode.
• Add team selection GUI and multiple new listeners (ConnunityHuntMovementListener, TeamSelectionGUIListener, TeamSelectionItemListener, HeadstartRestrictionListener, BedExplosionPreventionListener, and others) and wire them up in ChallengeUtil; also expose getters for new managers/listeners.
• Update StartCommand and TeamCommand to support Connunity Hunt mode (mode mutual-exclusion checks, auto-assignment, start/notify logic, spectator handling).
• Refactor FullResetCommand: perform folder deletion asynchronously, move Thread.sleep to async task, use boolean-returning deleteWorldFolder with NIO and improved error logging, add extra safety checks (abort on incomplete deletion), create data folders for new worlds/dimensions to avoid missing files, and ensure regeneration runs on the main thread.
• Avoid loading speedrun world at startup when reset.fullreset-on-startup is enabled to prevent unnecessary I/O and Windows file-lock issues.
• Register new commands/listeners and initialize new components in ChallengeUtil.
• Bump plugin version in pom.xml and update plugin language/resources and plugin.yml accordingly.

These changes add the new game mode features and harden the reset workflow to reduce failures on Windows and avoid re-opening deleted world files.
