Auto-Rewind for Daily NuttX Tests

To catch and fix bugs in Apache NuttX RTOS early, an automated rewind testing system was created. This system daily builds and tests NuttX; if a test fails, it backtracks through commits, rebuilding and retesting until the culprit is found. A Mastodon alert and a polite notification are then sent to the relevant NuttX developer. GitLab snippets and a Prometheus database track and analyze results, visualized in a NuttX dashboard showing build history.
