This commit addresses issue grafana#3552 by adding comprehensive testing for gRPC proto definition loading when k6 and gRPC server run in separate processes. Key changes: - Add TestGRPCSeparateProcess test that validates runtime proto loading - Move gRPC service from internal/lib/testutils to public testutils/grpcservice - Consolidate gRPC services to eliminate duplication (addresses @mstoykov feedback) - Update all import paths and proto file references throughout codebase - Fix context leak linting error in lib/executor/helpers.go - Update examples and tests to use new service location The refactor follows the MR feedback to reuse existing gRPC service infrastructure instead of creating duplicate implementations, making the codebase cleaner and more maintainable while enabling the separate process testing capability. Technical details: - Moved comprehensive gRPC service (FeatureExplorer + RouteGuide) to public package - Updated go_package option in proto files to reflect new location - Fixed all linting issues: errcheck, forbidigo, gofmt, gosec - Maintained backward compatibility for all existing functionality - Test validates core requirement: proto definitions loaded at runtime work correctly across process boundaries Closes grafana#3552

This test verifies that k6 can properly load proto definitions at runtime when the server and client are in separate processes. This ensures that we're not relying on the global registry being populated by the server process.
Fixes #3552
What?
This PR adds a new test (
TestGRPCSeparateProcess) that:Why?
Previously, gRPC tests ran both the server and client in the same process, which could mask issues with proto type registration due to Go's global registry. This test ensures that k6's gRPC client can independently load and use proto definitions at runtime, matching real-world usage and preventing false positives in tests.
