TelegramLogger v5.0.0 — Major Update

Bug Fixes

• Fixed duplicate Telegram messages — Messages from Telegram were sometimes delivered 2-3 times to Minecraft. Fixed with an atomic polling guard that prevents overlapping long-poll requests.
• Fixed `/sudo` command crashes — The sudo command would crash in non-forum groups. Now handles missing thread IDs gracefully.
• Fixed `/sudo` not showing output — Previously showed "executed successfully" but no output. Now captures and displays full command output using OutputCapturingSender.
• Fixed multi-line message prefix spam — Multi-line messages from Telegram had the prefix on every line. Now applied only once.

New Features

• Server Start/Stop Notifications — Get notified in Telegram when your server starts or stops
• First Join Detection — Special welcome messages for players joining for the first time
• Anti-Flood System — Configurable rate limiting (sliding window) prevents message flooding
• Sudo Output Capture — `/sudo` commands now show their full output in the Telegram response
• Sudo Blacklist — Block dangerous commands (`stop`, `op`, `ban-ip`, etc.) from remote execution
• TPS Command — Check server TPS and memory usage from Telegram with `/tps`
• Config Auto-Restore — Corrupt config files are automatically backed up, regenerated, and recoverable values are migrated

Code Improvements

• Full code restructuring — Monolithic 3000-line file split into 11 focused classes across 6 packages
• Modular architecture — Clean separation: config, telegram API, event handling, commands, data management, utilities
• HTML escaping — User input is properly escaped to prevent HTML injection in Telegram messages
• Better error handling — Graceful failure with clear error messages instead of silent crashes
