MultiProxySync

This update reworks proxy health tracking, adds update checking and bStats metrics, and migrates the API package coordinates.

✨ Added

• Added an update checker for new MultiProxySync versions
• Added bStats anonymous usage metrics
• Added the proxy_network_size custom bStats chart

⚡ Improved

• Migrated proxy registration from the legacy Redis Set to the multiproxysync:proxyList ZSET
• Proxies now register immediately on startup and refresh their heartbeat periodically
• Heartbeat timestamps now use Redis server time to avoid system clock differences between proxies
• Proxies inactive for more than 30 seconds are automatically treated as offline
• Proxy lists, player statistics, and API queries now only include active proxy nodes
• Improved shutdown cleanup by cancelling heartbeat tasks and removing the proxy from Redis

🔄 API Migration

• Maven Group ID changed from top.time-blog to net.time-cloud
• Java package changed from top.timeblog to net.timecloud
• API method signatures remain unchanged
• Plugins using the API must update their dependency coordinates and Java imports

🗺️ Version Direction

• The 2.3.x release line will remain focused on player count and player list synchronization
• Future 2.3.x updates will mainly provide maintenance, bug fixes, and stability improvements
• New feature expansion will continue in 3.0.0+
