Kristoffer Dalby bca6e6334d integration: add custom subnet support and fix exit node tests
Add NetworkSpec struct with optional Subnet field to ScenarioSpec.Networks.
When Subnet is set, the Docker network is created with that specific CIDR
instead of Docker's auto-assigned RFC1918 range.

Fix all exit node integration tests to use curl + traceroute. Tailscale
exit nodes strip locally-connected subnets from their forwarding filter
(shrinkDefaultRoute + localInterfaceRoutes), so exit nodes cannot
forward to IPs on their Docker network via the default route alone.
This is by design: exit nodes provide internet access, not LAN access.
To also get LAN access, the subnet must be explicitly advertised as a
route — matching real-world Tailscale deployment requirements.

- TestSubnetRouterMultiNetworkExitNode: advertise usernet1 subnet
  alongside exit route, upgraded from ping to curl + traceroute
- TestGrantViaExitNodeSteering: usernet1 subnet in via grants and
  auto-approvers alongside autogroup:internet
- TestGrantViaMixedSteering: externet subnet in auto-approvers and
  route advertisement for exit traffic

Integration testing

Headscale relies on integration testing to ensure we remain compatible with Tailscale.

This is typically performed by starting a Headscale server and running a test "scenario" with an array of Tailscale clients and versions.

Headscale's test framework and the current set of scenarios are defined in this directory.

Tests are located in files ending with _test.go and the framework are located in the rest.

Running integration tests locally

The easiest way to run tests locally is to use act, a local GitHub Actions runner:

act pull_request -W .github/workflows/test-integration.yaml

Alternatively, the docker run command in each GitHub workflow file can be used.

Running integration tests on GitHub Actions

Each test currently runs as a separate workflows in GitHub actions, to add new test, run go generate inside ../cmd/gh-action-integration-generator/ and commit the result.
