HostStartFailure

How the host was lost. Two arms because the repair differs: spawnFailed means no process ever ran (error is Node’s own spawn error — code ENOENT, EACCES, … — so fix the path or its permissions); hostExited means a process ran and ended before the handshake completed, and exit is its row — any row, the clean one included: a host that wrote its complaint to stderr and exited 0 before its first frame is still a lost host, and the row says only how it ended. answeredInitialize says whether it got as far as a usable initialize answer before dying (then the loss came while the SDK was completing the handshake, not at startup).
