🛡️ Sentinel: [security improvement]

[DerUntote]

🚨 Severity: MEDIUM
💡 Vulnerability: Internal RPC errors (err.message) from coin daemons were being passed directly to Discord users via message.reply(). This could leak sensitive server information, file paths, or infrastructure details.
🎯 Impact: Attackers could potentially gather information about the underlying system architecture or configuration by intentionally triggering errors.
🔧 Fix: Replaced message.reply(err.message) with console.error(err) and a generic "An internal error occurred." reply across all *Tipper.js modules. Added entry to .jules/sentinel.md.
✅ Verification: Ran node -c on all modified files to ensure no syntax errors were introduced. Checked via git diff that no sensitive info is leaked to the user.
