policy: DevOps "No-Deploy Friday" Safety Lock

[akarlaraytu]

📝 Context

An autonomous DevOps agent manages our deployments. To prevent weekend outages, we want a hard rule: No deployments to the "Production" environment on Fridays after 4 PM.

🎯 The Goal

Write a .csl file that blocks risky deployments based on time and environment.

Variables you can use:

• target_env (String): The environment (e.g., "STAGING", "PROD").
• day_of_week (String): Current day (e.g., "FRIDAY", "MONDAY").
• current_hour (Integer): 24-hour format (e.g., 16 for 4 PM).

Requirements:

1. MUST BLOCK if target_env is "PROD" AND day_of_week is "FRIDAY" AND current_hour >= 16.
2. Allow all deployments to "STAGING" or "DEV" regardless of time.
3. Allow "PROD" deployments on other days.

Hi! I’d like to work on this issue.
I’ve created a CSL policy that blocks PROD deployments on Fridays after 4 PM while allowing deployments to DEV and STAGING at any time and allowing PROD on other days.

Hey @sohamzope18 welcome aboard! 🚀

Thank you for stepping up and putting this together so quickly. Blocking Friday afternoon PROD deployments is I believe absolutely perfect real-world use case to demonstrate CSL's policy enforcement capabilities.

I have officially assigned the issue to you, and I am diving into your PR to review the code right now.

Thrilled to have you contributing to the ecosystem!

Amazing work on this policy, @sohamzope18 It is clean, practical, and perfectly demonstrates the power of CSL for real-world DevOps/Agent scenarios. This is exactly the kind of robust engineering we love to see.

We are thrilled to have you on board. You've officially earned your spot in the Contributors section at the top of our README, welcome to the Chimera ecosystem! 🚀

If you enjoyed writing in CSL and believe in the vision we are building here, we'd be truly honored if you gave the repository a star. ⭐

Merging this now. Looking forward to seeing more of your contributions in the future!
