📄 Description

Describe your changes

This PR introduces the ability to prevent the installation of the default route (0.0.0.0/0) into the system routing table while preserving the WireGuard AllowedIPs configuration by passing
--disable-default-route CLI arg.

This allows enabling an Exit Node on the peer without automatically routing all host traffic through the tunnel, enabling custom routing management outside netbird.

Summary by CodeRabbit

New Features
- New configuration option and CLI flag to disable installation of the system default route; the choice is persisted, surfaced via the daemon API, and, when enabled, prevents the client from adding the 0.0.0.0/0 default route.
Tests
- Added and updated tests covering the disable-default-route behavior across configuration, startup, and route-management scenarios.
