[FEATURE] Create ARCHITECTURE.md documentation

[rohitkumarnaidu]

Feature Request

Description
As Aarini grows in complexity, it becomes harder for new contributors to understand the high-level design and how the different components fit together.

Proposed Solution

• Create an ARCHITECTURE.md file in the root directory.
• Document the tech stack, the main folders/modules, and the data flow.
• Briefly explain how the frontend, backend, and any external services interact.

Benefits

• Greatly accelerates the onboarding process for new developers.
• Serves as a reference point for architectural decisions.

Could you please assign this issue to me and add the ELUSOC label? I will raise a PR with the drafted documentation. Thanks! 🚀

Closing - the repo already has an ARCHITECTURE.md file. My mistake for not checking first. Sorry about that!

Ah sorry, I accidentally hit close while organizing my issues! I am definitely still working on it and will submit a PR. Apologies for the confusion!
