nostr-tools PR #507 adds reconnect callbacks
nostr-tools PR #507 was closed, adding `enableReconnect`: relay disconnects can now trigger exponential-backoff reconnection attempts. The PR also fixes `enablePing` and adds basic tests.
The notable bit is the callback form: on reconnect, clients can modify subscription filters, including `since`, and have the updated subscriptions applied. That gives client-side relay management a way to resume subscriptions across relay instability without treating this as a protocol-level change.
Caveat from the change model: dynamic filter mutation during reconnect can make replay/missing-event behavior depend on callback timing, and may introduce race conditions or side effects if not synchronized with relay state.
