[deps] Update google.golang.org/grpc from v1.75.0 to v1.79.2

[github-actions]

Summary

Update the indirect google.golang.org/grpc dependency from v1.75.0 to v1.79.2.

Current State

• Package: google.golang.org/grpc
• Current Version: v1.75.0 (indirect)
• Proposed Version: v1.79.2
• Update Type: Multi-version minor jump (v1.75.0 → v1.79.2)

Why Separate Issue

⚠️ Multi-version jump requires careful testing

• Spans 4 minor versions (v1.75 → v1.79) with accumulated changes
• gRPC changes can affect serialization, connection management, and performance
• Multiple new features and behavior changes across versions
• Needs thorough testing for any gRPC-related integrations

Safety Assessment

⚠️ Requires careful review

• Multi-minor-version jump increases risk of subtle behavior changes
• gRPC is a core transport layer; changes can affect connectivity and reliability
• Review all intermediate release notes before upgrading
• Confirm no changes affect the MCP SDK integration (which uses gRPC under the hood)

Changes

Notable changes across v1.75 → v1.79:

• v1.76+: Various balancer and connection management improvements
• v1.77+: Enhanced observability and OpenTelemetry support
• v1.78+: Performance improvements
• v1.79.2: Bug fix — prevent redundant error logging in health/ORCA producers by skipping stats/tracing processing when no stats handler is configured

Links

• v1.79.2 Release
• Package Repository
• [Go Package]((pkg.go.dev/redacted)

Recommended Action

go get -u google.golang.org/grpc@v1.79.2
go mod tidy

Testing Notes

• Run all tests: make test
• Verify MCP server connections still work
• Test any gRPC-based integrations (google.golang.org/genai, cloud.google.com)
• Check for connection lifecycle issues
