Add a user manual, and correct the lap timing row The User Manual page was an empty placeholder. It is now a parent index with seven sub-pages covering every screen and every setting: getting started, navigation, the seven modes, the session screens, settings, tracks and diagnostics. Written for somebody holding the device rather than reading the source, so it leads with the two things that surprise people: only a press-and-hold opens the menu, and no circuit in the supplied pack will time a lap because every one of them is provisional. Both are deliberate, and the manual says why rather than just what. Also corrects a row that had gone stale. The timing engine is no longer waiting on a consumer - fixes reach the timing task and lap events drain back. What is still missing is a circuit whose geometry has been validated, which is a different blocker and now says so.
