adds NetFlow functionality to track and log network traffic information between peers, with features including:
- Flow logging for TCP, UDP, and ICMP traffic
- Integration with connection tracking system
- Resource ID tracking in NetFlow events
- DNS and exit node collection configuration
- Flow API and Redis cache in management
- Memory-based flow storage implementation
- Kernel conntrack counters and userspace counters
- TCP state machine improvements for more accurate tracking
- Migration from net.IP to netip.Addr in the userspace firewall
* [client] Support Extra DNS Labels for Peer Addressing
* [management] Support Extra DNS Labels for Peer Addressing

In the case of user space WireGuard mode, use in-memory proxy between the TURN/Relay connection and the WireGuard Bind. We keep the UDP proxy and eBPF proxy for kernel mode.
The key change is the new wgproxy/bind and the iface/bind/ice_bind changes. Everything else is just to fulfill the dependencies.
previously, we called the restore method from the startup when there was an unclean shutdown. But it never had the state keys to clean since they are stored in memory
this change addresses the issue by falling back to default values when restoring the host's DNS
On macOS use the recommended settings for providing split DNS. As per
the docs an empty string will force the configuration to be the default.
In order to to support split DNS an additional service config is added
for the local server and search domain settings.

* Add faster availability DNS probe and update test domain to .com
- Count success queries and compare it before doing after network map probes.
- Reduce the first dns probe to 500ms
- Updated test domain with com instead of . due to Palo alto DNS proxy server issues
* use fqdn
* Update client/internal/dns/upstream.go

* compile client under freebsd (#1620)
Compile netbird client under freebsd and now support netstack and userspace modes.
Refactoring linux specific code to share same code with FreeBSD, move to *_unix.go files.
Not implemented yet:
Kernel mode not supported
DNS probably does not work yet
Routing also probably does not work yet
SSH support did not tested yet
Lack of test environment for freebsd (dedicated VM for github runners under FreeBSD required)
Lack of tests for freebsd specific code
info reporting need to review and also implement, for example OS reported as GENERIC instead of FreeBSD (lack of FreeBSD icon in management interface)
Lack of proper client setup under FreeBSD
Lack of FreeBSD port/package
* Add DNS routes (#1943)
Given domains are resolved periodically and resolved IPs are replaced with the new ones. Unless the flag keep_route is set to true, then only new ones are added.
This option is helpful if there are long-running connections that might still point to old IP addresses from changed DNS records.
* Add process posture check (#1693)
Introduces a process posture check to validate the existence and active status of specific binaries on peer systems. The check ensures that files are present at specified paths, and that corresponding processes are running. This check supports Linux, Windows, and macOS systems.
