The async settings gate added in f0d96f8e called
shouldStartDaemon() inside Promise.resolve(...).then(...) with no
catch. If loadDesktopSettings() rejects (corrupted JSON, FS error),
the daemon never starts, no error renders on the splash, and the
retry button repeats the same silent path.
Add a recordError method to DaemonStartService and an onGateError
callback to startDaemonIfGateAllows / startHostRuntimeBootstrap.
_layout.tsx wires it through so a gate rejection populates
lastError, the splash shows the failure, and retry has signal.
