Detailed Description of the Pull Request / Additional comments

Validation Steps Performed

Mirrored route tracking used an incomplete comparator that considered only route class, destination address, and metric. Distinct routes with different prefix lengths or next hops could therefore be treated as equivalent and silently omitted. The fix preserves the existing route-class ordering while using the complete EndpointRoute comparison for route identity. Regression tests cover prefix length, next hop, metric, exact duplicates, and dependency ordering.

This PR adds a "search or file issue on github" suggestion in all user visible errors to: Help users find solutions faster. Collect more user reported issues to help reliability improvements. This PR also updates all tests checking the error message to use a unified function for creating the expected error message.

…led (#41491) In systemd v261, the systemd's tmpfiles.d/x11.conf was changed from D! to D. systemd/systemd@5474cad. This means the systemd-tmpfiles command will try to execute it when called out of the boot sequence. In the linked issue's case, it's called by the post install script by dpkg. This will fail as the wsl override is not in place when systemd is disabled. This PR enables the wsl override file generation for all distros with wslg enabled, regardless of if the distro boots with systemd.

* Fix unvalidated TerminalProfileSize when importing a distribution _ProcessImportResultMessage constructed the terminal profile string_view using the message-supplied TerminalProfileSize without validating it against the received buffer length. Use the bounds-checked two-argument span::subspan() overload (matching the existing ShortcutIconSize handling a few lines above) so an inconsistent size value throws instead of producing a string_view that runs past the end of the buffer.

In 2.9.8, the distro processes are separated into their own cgroups. But they remain in the same cgroup namespace. That caused compatibility issues with softwares that assume a fixed systemd cgroup layout. For example, rootless docker and nerdctl. Fixes on Moby and nertctl are being worked on. However, to avoid issues with other software, WSL's cgroup handling should also be improved. This PR creates new cgroup namespaces for the distros. So, to the non-critical distro processes, the systemd cgroup layout stays the same as before. This PR also introduces a cgroup structure change to accomplish this. The systemd init is moved from wsl-user/distro-N/systemd to wsl-user/distro-N. And the initialization of the distro-N controllers is handled by systemd instead. The processes are also moved into the non-systemd cgroup in systemdless distros. This makes sure that sub-group controllers can be enabled in the distro root. Cgroup v2 is now enforced when distro isolation is enabled. Instead of constructing an unusable cgroup v1 layout when cgroup v1 and distro isolation are both enabled.

Before this change, an additional 10ms delay was added in the port tracker loop presumably to make the main loop slower than the worker loop. So, the worker result does not get super dated. This is not reliable. And the 10ms delay also slows down every consecutive bind call. This PR refactors the thread synchronization method. So, the timing between those two loops is more deterministic. And removes the performance penalty for all bind calls.
