Subject: [PATCH] register clearpilot memory params and seed defaults in
 manager_init
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Scaffolding for the upcoming UI port. Registers the keys the new C++
UI and SpeedState daemon will read/write, and seeds /dev/shm/params
defaults at manager start so first-readers don't see missing keys
before writers spin up.

Keys registered: CarIsMetric, ClearpilotCruiseWarning,
ClearpilotCruiseWarningSpeed, ClearpilotHasSpeed, ClearpilotIsMetric,
ClearpilotPlayDing, ClearpilotShowHealthMetrics,
ClearpilotSpeedDisplay, ClearpilotSpeedLimitDisplay,
ClearpilotSpeedUnit, DashcamFrames, DashcamShutdown, DashcamState,
IsDaylight, ModelFps, ModelStandby, ModelStandbyTs,
ScreenRecorderDebug, ShutdownTouchReset, TelemetryEnabled, VpnEnabled.

PERSISTENT registration here is purely a no-op placeholder: the actual
storage is /dev/shm/params (tmpfs), which clears on every reboot
regardless. Bench-mode keys (Bench*, ClpUiState, LogDirInitialized)
not registered yet — they'll come with their respective features.
