feat: add SDK metrics service and update telemetry configuration

- Introduced a new service for SDK metrics in values.yaml, enabling metrics collection on port 9091.
- Updated the worker.py to initialize a new runtime with Prometheus metrics configuration for the SDK metrics server.
- Adjusted environment variable for GITHUB_BRANCH to reflect the current focus on testing and performance design.
