- Fix DNS resolver leaks by creating temporary resolv.conf files within the profile's runtime directory and ensuring robust cleanup.
- Fix isolation block directory leaks by explicitly removing the block directory during namespace unpinning.
- Improve namespace lifecycle management:
- Register processes before joining an active namespace to prevent race conditions in reference counting.
- Update `IsLastProcess` and corresponding tests to reflect the unregister-then-check cleanup flow.
- Improve test reliability and correctness:
- Convert `TestAppRun_ProfileDirInjection` to use separate binary execution, preventing process replacement and ensuring `t.TempDir()` cleanup.
- Replace hardcoded test configuration paths with `t.TempDir()` in `mount_leak_test.go`.
- Implement `SetEnvOverrides` helper for cleaner environment variable management in E2E tests.
- Improve E2E lifecycle tests with better environment handling and output redirection.

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

- Security: Eliminate namespace escape risk by removing `HostBind` and enforcing `FDBind` using pre-opened host socket FDs.
- Security: Replace unsafe `atoi` with `strtol` and strict validation in the C launcher to prevent malformed PID joins.
- Stability: Fix PID wraparound by storing session timestamps in PID files to detect recycled PIDs.
- Stability: Resolve DNS mount leaks by implementing proper unmounting of `/etc/resolv.conf` during tunnel shutdown.
- Performance: Optimize `FDBind` throughput by implementing batch packet processing in the receive loop.
- Deployment: Implement `memfd_create` for the C launcher to support `noexec` temporary directories and reduce disk I/O.
- Maintenance: Replace external `ip` CLI dependency with native `netlink` library for robust network configuration.
- Quality: Fix all `golangci-lint` errors and replace remaining panics with explicit error handling.

- Replace marker-file pinning with kernel bind-mount anchors for reliable namespace persistence.
- Implement atomic "last-man-out" cleanup sequence using ProfileLock, preventing namespace leaks and race conditions.
- Add comprehensive resilience test suite covering:
- Crash recovery from stale runtime state.
- Host network change stability.
- Configuration hot-swap session persistence.
- Resource exhaustion and high-churn lifecycle stress.
- Align documentation and test expectations with rootless session-based persistence.
- Fix argument integrity and isolation leaks.
- Ensure 100% pass rate for all E2E and integration tests.
