Architecture: - Introduced NetworkManager and NetworkOps interface in internal/network to abstract netlink calls. - Introduced MountOps and FileSystem interfaces in internal/namespace to abstract mount and filesystem operations. - Introduced TunnelManager in internal/wireguard to coordinate tunnel lifecycle using the new abstractions. - Updated internal/cli and internal/manager to use these managers. Testing: - Restored t.Parallel() to unit tests in internal/network and internal/wireguard. - Implemented setupParallelEnv and an enhanced mockFS in wireguard_unit_test.go to ensure complete test isolation. - Added bootstrap_test.go to verify launcher preparation logic in internal/namespace without requiring syscall.Exec. - Resolved data races in internal/network tests. CLI: - Added support for -h, --help, and -help flags for the main command. Verification: - Passed all tests (unit, integration, E2E). - Verified zero data races with 'go test -race'. - Passed golangci-lint and go vet.
