Drop added code comments

- Remove the Javadoc and inline comment blocks the three runtime-safety commits added under src/main
- Keep the GPL file header on the new spi type, matching every other file in that module
- Leave the superseded stale-temp ordering comment deleted rather than restoring text the new boot path contradicts
