worker.process now logs each of the seven failure reasons it already had
(unknown stream, missing id, account mismatch, read_email err/None,
telegram send failure) without echoing credentials, so the delivery tail
can be diagnosed from stdout alone. notify.rs /worker now logs the
retry_or_dlq outcome it previously discarded, and logs each
commit/ack step. Fixes two formatting slips in the new code: a read
error logged with ?error (Debug) instead of %error (Display), and a
reconcile error line that misattributed old_state to the position walk
it actually discarded.
