Subscribe/unsubscribe intermittently showed an error but "worked after refresh":
the kind-30000 list event WAS sent and persisted, but when no relay ACKed it
within the 10s window, assertAnyRelayAccepted threw -> toggleChannel threw -> the
button handler reverted the optimistic UI and showed "Failed to update your
subscriptions." The event was on the relays the whole time (hence the refresh).
Fix: in publishSubscriptionList, distinguish an all-timeout (unconfirmed) result
from an explicit rejection. The list is an idempotent, replaceable event that was
already sent + locally cached, so an all-timeout is treated as a SOFT SUCCESS
(record the event id, no throw, reconciles on next load) instead of a hard error.
Only an explicit relay rejection (or a pre-publish signer/encryption error, thrown
earlier) still fails loudly. New exported classifier
subscriptionPublishFailuresAreAllTimeouts().
Tests: tests/subscription-publish-timeout.test.mjs (5 — all-timeout=soft,
any-rejection=hard, empty=hard, case-insensitive).
Note: assertAnyRelayAccepted is used the same way by userBlocks/app list publishes
— they likely have the same false-negative and could get the same treatment later.
