The version number in the app is honest again
A small but real fix. The version shown in the About box and Settings had been a hand-maintained number in the code, and it had quietly drifted: it read 0.1.80 while the app was actually several releases newer. That is worse than a cosmetic wrong number, because the same value is what the update check compares against - so an install could be offered an 'update' to a release it was already running. The version is now derived from the build itself, so it can never drift from the real version again: the number in the app, the number sent with opt-in stats, and the number the update check compares are all the one true build version. The one-press self-update was also verified end to end on a real install - an older build downloaded the signed bundle, installed it OVER itself in place (no second copy left behind), and relaunched into the new version with tabs and history intact. No engine or web-platform change, so every parity figure holds.
