Prevent the ambiguity where a mistyped subcommand was interpreted as the target
wrapped process.
- Introduce `run` and `exec` (alias) subcommands for launching wrapped processes.
- Promote internal test commands (`test-ns`, `test-args`, `test-lifecycle`) to explicit subcommands.
- Update CLI routing to return an error for unknown subcommands instead of falling back to the default execution path.
- Update `README.md` usage examples and all test suites to use the new subcommand structure.

- Introduce `namespace.Ops` interface to decouple `Manager` from system-level namespace operations, enabling easier unit testing via mocks.
- Add unit tests for `internal/paths` to verify path resolution logic across different environment configurations.
- Implement `EnsureBinary` helper in E2E tests to gracefully skip tests when `WG_WRAP_BIN` is not set, allowing `go test ./...` to pass in non-build environments.
- Apply project-wide formatting and fix linting issues.

public domain license
- Update go.mod and all internal imports to reflect the new module path
- Add LICENSE file with the Unlicense (public domain dedication)
- Increase timeouts in e2e lifecycle tests to prevent flaky failures
- Verify all tests, linting, and formatting pass with the new module name

- DNS Leak / Isolation Bypass: Blocked glibc's systemd-resolved and
D-Bus socket communication within the unprivileged mount namespace by
introducing BlockHostServices(). This targeted mount-blocking forces
glibc to fall back to the standard resolv.conf DNS routing path and
prevents host leaks.
- Lifecycle Race: Reordered and protected the reference-counting
cleanup routine under the profile flock to ensure that check-and-unpin
operations are atomic and do not teardown namespaces actively used
by parallel processes.
- Editor Arguments: Split the EDITOR environment variable into discrete
field tokens before invocation to support editor configurations
containing command-line flags.
- Testing: Added E2E regression tests for DNS leak detection,
namespace unpinning concurrency, and editor argument parsing. All E2E
tests now compile and pass cleanly.
