v0.6.25
feat: drop Engine RPM from the default Main page Engine RPM now has its own per-instance Engine sections, so it is redundant on the Main overview. Remove it from the bundled example Main container and shift the remaining row-0 signals (Speed/Depth/Water Temp) left to fill the gap. (The user's existing workspace file is updated separately on their machine; scaffold never overwrites an existing workspace.) Bumps to 0.6.25.
