Pull request overview

Adds shared ADNL peer address resolution logic and wires it into fast-sync and custom overlays, improving overlay peer discovery while also extending RLDP diagnostics for long-running/timeout-masked transfers.

Changes:

• Introduced a reusable background “overlay peer resolver” task in NodeNetwork that DHT-resolves peer ADNL addresses and registers them in ADNL via the overlay layer.
• Integrated the resolver into fast-sync overlay updates (with cancellation management) and refactored custom overlays to use the shared resolver instead of a local worker.
• Added additional RLDP warnings to diagnose transfers that appear to “mask” timeouts or run excessively long.
