Ray tracing with f64. The canonical data rounds the coordinates to one decimal and the angles to three, so the intended beam is never exactly collinear and the check needs a tolerance of about 0.1. The stub and the example both document this. Registers the exercise in config.json. Verified with bin/verify-exercises-in-docker (the current test runner image) and with V 0.5.2 for bin/test. configlet lint passes, and v fmt -l / v vet are clean on the new files.
