🛡️ Sentinel: [security improvement]

[DerUntote]

🚨 Severity: MEDIUM
💡 Vulnerability: The application was exposing internal paths and potentially sensitive execution contexts in two ways: first, by appending e.stack to msgTxt which is subsequently sent to a Discord moderation channel when debug config is enabled. Second, by printing raw RPC err.message details directly to users via message.reply() in all tipper modules when transactions failed.
🎯 Impact: Exposing server directory structures, internal library paths, or daemon status states can provide an attacker with valuable information during reconnaissance.
🔧 Fix: Replaced the stack trace concatenation in bot/bot.js with a local console.error(e) call. In bot/modules/*Tipper.js, replaced message.reply(err.message) with message.reply('An error occurred.') while logging the real error internally. Additionally added .catch(() => {}) to all message deletes to avoid unhandled rejections if messages were already removed. Added a journal entry about this fix in .jules/sentinel.md.
✅ Verification: Verified by running Prettier, followed by a manual syntax verification node -c bot/bot.js. Verified .jules/sentinel.md journal entry was correctly appended via cat.
