improve: detect and skip negentropy for unsupported relays

- Upgrade NOTICE log level to INFO when relay rejects negentropy (envelope/NEG- errors)
- Track NIP-77 support status per relay connection to avoid repeated failed attempts
- Mark relay as unsupported when NOTICE rejection or timeout occurs
- Skip negentropy on subsequent syncs during same connection session
- Reset support status on reconnect to allow retry after relay upgrades

This reduces log noise and eliminates 10-second timeout delays on each historic
sync attempt for relays that don't support NIP-77 negentropy.

Fixes negentropy-timeout-10-seconds issue by learning from relay behavior.
