up 7.24.3

CoreManager.RunProcess decided sudo elevation from the live mutable
_config.TunModeItem.EnableTun while the launched config was generated
from the immutable CoreConfigContext snapshot. If the TUN state changed
while a reload was in flight, a core whose config contains a TUN
inbound could launch without elevation and die within the 100ms health
check ("Failed to run core"), with no stderr shown.

The elevation decision now follows context.IsTunEnabled /
preContext.IsTunEnabled, so the generated config and the launch mode
always agree. With legacy TUN protect, the sing-box pre-core hosting
TUN is elevated and the main core no longer runs as root needlessly.
