  "message": "go: preserve race mode for go_source rules (#4674)\n\n**What type of PR is this?**\n\nBug fix\n\n**What does this PR do? Why is it needed?**\n\n`go_source` calls `go_context(..., maybe_needs_cc_toolchain \u003d False)`\nand intentionally does not declare a C/C++ toolchain. `go_context` still\ntreated the undeclared toolchain as unavailable, forced pure mode, and\nrejected race instrumentation. Preserve the configured mode for rules\nthat opt out and do not declare the C/C++ toolchain while retaining\nmissing-toolchain validation for normal Go rules. Add race-mode\nregression coverage for both standalone `go_source` and an embedding\n`go_library`.\n\n**Which issue(s) does this PR fix?**\n\nFixes #4673\n\n**Other notes for review**\n\nValidated with:\n\n```\nbazel test --jobs\u003d2 --local_test_jobs\u003d1 //tests/core/race:race_test //tests/core/starlark/cgo:missing_cc_toolchain_explicit_pure_off_test\n```",
