I killed ARTEX on my lunch break

I started Sentinels on a lunch break. It's a host intrusion detector for Linux, macOS and Windows, written in Rust and released under the MIT license. It's meant to deal with automated attacks from tools such as ARTEX. The agent watches processes and connections on the machine and can stop a malicious process and its children. It can also quarantine files and disable supported startup entries associated with the attack. Those cleanup changes can be reversed. The stopping times I'm seeing in internal tests are about 20 ms for rapid process chains and under 5 ms for selected tooling tests. I'll add the benchmark setup and results to the README. You can use it on a single machine or run the fleet service yourself. Managed hosting is available too. AI analysis is optional; the default stop decision happens locally. The repository has the source and installers. The manual covers setup and the response modes. GitHub: https://github.com/gary23w/sentinels
