The play-probe now lands (iPhone: iOS 18.7 Safari, hls.js path, MSE ok),
but the /stream XHR never reaches the server on the failing attempts —
impossible under the known code path. Instrument each step
(new-hls-ok / loadsource-called / attach-ok) and log EVERY hls.js error
(fatal+non-fatal, with retry counter) so the client timeline is visible
server-side. Also fixed JSV constant drift (was stuck at 10).
events endpoint: accept hls-err, forward step/fatal/details/buffer/retry/http.
