Feature Spec: Service Mesh Interop

Summary

Enable inter-service communication: Chat Service validates tokens via auth-svc, and pushes async tasks to the PostgreSQL job queue for Worker to process.

Requirements

1. Auth-svc /validate endpoint: Auth Service exposes POST /api/auth-svc/validate that accepts a Bearer token and returns the validated user info.
2. Chat-svc token validation: Chat Service calls http://auth-svc/api/auth-svc/validate via pkg/svc client to check tokens on protected endpoints.
3. Chat-svc queue producer: Chat Service pushes jobs to the PostgreSQL queue (via pkg/queue) for async processing by Worker.
4. Worker job processing: Worker registers a handler for chat_task job type and processes tasks from the queue.

Non-Goals

• No new database schemas beyond existing jobs table
• No Redis (using existing PostgreSQL queue)
• No new frontend changes

Acceptance Criteria

• Auth-svc has a /validate endpoint that validates JWT tokens
• Chat-svc calls auth-svc to validate tokens on protected routes
• Chat-svc can enqueue jobs to the queue
• Worker processes chat_task jobs
• All components have tests
• All tests pass
