This PR improves the reliability of Cosmos DB Emulator startup in GitHub Actions CI/CD workflows by implementing retry logic, extended timeouts, and better diagnostics. The changes address intermittent failures when starting the emulator during automated testing.

- Added comprehensive retry logic with up to 3 attempts and cleanup between retries
- Increased timeout from 4 minutes to 10 minutes per attempt
- Added detailed status monitoring and diagnostic logging
- Included a trivial comment change to the C# file to trigger CosmosDB emulator testing
