🛡️ Sentinel: [MEDIUM] Fix Error Stack Trace Leakage

[DerUntote]

🚨 Severity: MEDIUM
💡 Vulnerability: Unhandled exceptions in bot commands appended the full e.stack trace to moderation log messages on Discord when config.debug was true, exposing server file paths and internal architecture.
🎯 Impact: Malicious users could potentially exploit detailed knowledge of the internal architecture and server file paths if they gained access to the logs.
🔧 Fix: Changed the error handling block in bot/bot.js to log the full stack trace internally using console.error instead of sending it externally.
✅ Verification: Ran syntax validation and manually reviewed the code to ensure stack traces are no longer added to msgTxt.
