Abdul WahabandClaude Opus 5 8397d532b9 Keep the unsupported-node notice to the harness that can render it ...

`systemMessage` on stdout is a Claude Code contract. The shared guard was
emitting it for Codex and Cursor too, where what a harness does with stdout
it did not ask for is unconfirmed, and a Cursor preToolUse hook printing an
unexpected JSON object is the wrong thing to guess about.

Pass the notice in per harness instead of baking it into the guard. Claude
manifests opt in; Codex and Cursor take the runtime probe alone, so an
unsupported runtime stays as quiet there as it was before the probe existed.
Giving them their own shape later is one more argument at the call site.
