[Reviewed] fix: halt deployment on command load error (Issue #40 - Item 1)

[Ramanand-Shirbhate]

This PR addresses Item #1 from the Critical & Enhancement Bounty Board (#40).The Issue:
Previously, if src/deploy-commands.js failed to load commands, it would catch the error, log it, and continue the deployment process. This resulted in silent failures where incomplete command sets were deployed to Discord. The Fix:
Added process.exit(1) inside the catch block to ensure the Node process halts immediately upon a command load failure, preventing partial deployments. Fixes #40 (Item 1)

🔴 Critical: Deployment Fix Has Fatal Flaw

While the intention to prevent partial deployments is good, process.exit(1) in the catch block violates Node.js event loop contract and can corrupt in-flight operations. Node.js deployments (PM2, systemd, Docker) expect graceful shutdowns, not hard exits.

✅ Good

• Error message now includes context: 'Error loading commands:', error
• Addresses the silent failure issue

🟡 Warnings

• Missing newline at EOF causes "No newline at end of file" warning

🔴 Critical Issues

File: src/deploy-commands.js - Line 23

Issue: Using process.exit(1) crashes the process immediately
Consequence:

• Forces host managers into hard-kill recovery loops
• Prevents graceful shutdown and cleanup
• May lose process exit code context
  Fix: Use process.exitCode = 1 and allow natural exit

[Ramanand-Shirbhate]

Great catch regarding the Node.js event loop contract! You are entirely right—hard exiting can definitely cause issues with PM2/Docker cleanups.
I've pushed a commit that swaps it to process.exitCode = 1 to allow for a graceful shutdown, and I also added the missing EOF newline to clear out that warning. Let me know if it looks good to merge now!

This change is a step in the right direction, but process.exitCode = 1 does not actually stop execution. The script will continue to run and exit cleanly after the IIFE finishes. This can still result in partial deployments if the error occurs early.

The correct approach is to use process.exit(1) (without the Code suffix) to immediately terminate the Node.js process and prevent any further execution.

Suggested change:

- process.exitCode = 1;
+ process.exit(1);

This ensures the deployment halts immediately on any command load failure, preventing silent partial deployments as intended.
