[ENHANCEMENT] Add request ID tracking for better debugging and traceability

[Lochit-Vinay]

Description

Currently, there is no way to trace a request across logs and processing steps.
This makes debugging difficult, especially when handling multiple concurrent requests.

Proposed Solution

Introduce a unique request ID for every incoming API request.

Suggested Implementation

• Generate a UUID for each request
• Attach it to:
  • logs
  • responses (optional)
• Use middleware to inject request ID

Example

Response:
{
  "request_id": "abc-123",
  "data": {...}
}

Benefits

• Easier debugging
• Better observability
• Helps track failures across pipeline stages

Note

I didn’t find any existing issue related to request tracing or request IDs.
