Refactor GitHub Actions workflows to streamline build configurations

- Removed redundant CGO_ENABLED environment variable from jobs in e2e-tests.yml.
- Added CGO_ENABLED=0 to build commands in unit-tests.yml for cross-compilation consistency.
- Enhanced logging in manager.go by changing warning to debug level for disconnected clients.
- Optimized GetTotalToolCount method to minimize network calls during shutdown.
