useHostRuntimeSession returned the full HostRuntimeSnapshot, causing
every consumer to rerender on any internal state change (probe cycles,
client generation bumps). Replace with targeted hooks that return
primitives/stable references so useSyncExternalStore skips rerenders
when the subscribed value hasn't actually changed.
New hooks: useHostRuntimeClient, useHostRuntimeConnectionStatus,
useHostRuntimeLastError, useHostRuntimeAgentDirectoryStatus,
useHostRuntimeIsDirectoryLoading. Existing useHostRuntimeIsConnected
already followed this pattern.
useHostRuntimeSnapshot kept only for settings-screen where probe
data is legitimately needed.
