* fix(events): keep a share's prefix out of handle subscribe errors and limits A `kv:<handle>:<key>` pattern is now checked against the 256-character limit as the holder wrote it, before it's composed onto the shared prefix. The composed pattern is compiled with room for the longest prefix a grant can carry, at subscribe and at dispatch, so neither the limit nor its error depends on the prefix. A handle subscription's `match` is read off the holder's own subject instead of the stored composed pattern, so whether it's `null` no longer depends on how deep or long the prefix is. * fix(events): cap and end session subscriptions made through a share handle Session subscriptions made through a share handle are indexed under the handle in the owner's keyspace. A holder may keep 100 of them through one handle across all their connections; past that, subscribe fails with `events_subscription_limit`. The owner's own subscriptions through the handle don't count. Retiring a handle now ends its session subscriptions in the same region and sends `events.ended` with `permission_revoked`, alongside the existing durable settle. A socket refresh no longer renews a row whose handle was retired or whose grant is gone: it ends it the same way, which is how a retire made elsewhere reaches these rows. * fix(kv): read a forgotten share handle from the primary After a handle or its owner is forgotten, reads of that handle go to the primary for the next minute, so a replica that hasn't caught up can't put the old row back in the cache. A read that a forget lands on while it's in flight is answered but not cached. * fix(events): read a socket ref's subId after the last `|` A KV token carries the subscribed key, which can contain `|`, so splitting the ref at the second one cut the token short. A subscription on such a key couldn't be unsubscribed, and a reap left its row behind in the owner's keyspace. SubIds never contain `|`, so the ref is split at the last one.
