events v1.6.1-aio.16 — nostr publish reliability

Adds the entry alongside aio.15; older versions stay resolvable for
instances still running them.

Covers aiolabs/events #54 and #55: skipped publishes log at WARNING
instead of returning silently, events.nostr_publish_pending marks a row
from before each publish attempt until a confirmed success, and a
5-minute sweep republishes whatever is still flagged. Carries migration
m003.
