Respect Node asynchronous exec/execFile method-default stdio instead of interpreting an ignored option. Remove the superseded callback-shape query while preserving caller input, Evidence, uncertainty, argv and fork controls. Independently validated on current main through actual Node pipe capture, matching real-app CLI/MCP facts, 81 targeted tests and static checking. Closes#7217.
Preserve observed failed-response HTTP status through Linux Hopper setup diagnostics without changing download rejection, retry, or installation policy. Independently validated on latest main through red/green regressions, actual TLS sockets, focused checks and CI. Closes#7182.
