A small improvement to the opt-in anonymous telemetry: alongside the existing per-week sync bucket, the weekly ping now includes a lifetime sync bucket. Until now, an instance reporting zero syncs in a week was indistinguishable from one where syncing never worked at all; the lifetime bucket separates the two, so setup problems can be spotted and fixed. Same privacy rules as everything else: a coarse bucket only (0, 1-10, 11-100, 100+), never exact numbers, and nothing is sent unless you opted in.
