The TofuPilot CLI is now open source

The CLI that runs, deploys, and manages your test procedures is now fully open source under the MIT license, so you can read the code, build it yourself, and contribute.

• Published the CLI at github.com/tofupilot/cli with prebuilt binaries for macOS, Linux, and Windows
• Added contributor docs, an architecture guide, and a security policy
• Unified internal error handling and expanded the test suite for a cleaner, more reliable codebase
