3 days	refactor: implement dependency injection and enable parallel testing	James O'Doherty
	This commit refactors the core system operations to use a manager-based dependency injection pattern, eliminating global state and resolving data races in the test suite. 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.
11 days	refactor: remove dependency on ip CLI tool and abstract network logic	James O'Doherty
	Eliminate the external dependency on the `ip` (iproute2) command-line tool by centralizing network configuration and diagnostics within a new `internal/network` package using the `netlink` library. Changes: - Introduced `internal/network` package to handle network interface listing and configuration. - Replaced `exec.Command("ip", "link")` in `internal/namespace.VerifyIsolation` with `network.ListInterfaces()`. - Improved `VerifyIsolation` to explicitly ensure only the loopback interface is present in a fresh network namespace. - Moved interface and routing configuration logic from `internal/wireguard` to `internal/network`. - Removed unnecessary `os/exec` imports from network-related files. This change increases the tool's portability by removing the requirement for `iproute2` to be installed in the target environment.
